Description

Technical Field

[0001] This invention relates to the technical field of astronomical telescope equipment, and more specifically to an intelligent astronomical telescope. Background Technology

[0002] As a mainstream choice for entry-level astronomical observation equipment, astronomical telescopes are widely used by amateur astronomers for daily observation and beginner astrophotography due to the optical advantages of low-dispersion glass, as well as their small size, portability, and cost-effectiveness. However, existing astronomical telescopes have many intractable technical shortcomings that prevent them from meeting the demands for intelligent, convenient, and high-quality observation.

[0003] First, the focal length is fixed, requiring a large number of accessories such as external focal reducers, telephoto lenses, field flat lenses, and filters. The disassembly and assembly are cumbersome, which can easily cause optical axis misalignment. Repeated focusing and calibration are required, resulting in high usage costs.

[0004] Secondly, the operation method is outdated. Optical switching and filter replacement mostly use external mechanical levers and manual disassembly and assembly structures, which are not only cumbersome to operate, but also damage the lens barrel seal, causing dust to enter and the lens to become contaminated. At the same time, the mechanical structure is prone to loosening and optical path misalignment after long-term use.

[0005] Third, the level of intelligence is low, there is no matching automatic star-finding and tracking structure, it is impossible to achieve automatic celestial body positioning and long-term exposure tracking, and manual star-finding is difficult and the observation efficiency is low.

[0006] Fourth, the image quality is poor. It lacks a built-in permanent flat field structure and cannot achieve synchronous correction across all focal lengths, making it prone to edge distortion and chromatic aberration.

[0007] Fifth, it has low functional integration. Switching between visual and imaging modes requires disassembling and assembling accessories, making one-click switching impossible. It also relies heavily on external cameras, requiring dedicated interfaces, and does not support real-time wireless image transmission and intelligent control, resulting in a very poor user experience.

[0008] To address the shortcomings of the existing technologies, there is an urgent need for a fully sealed, electrically controlled, intelligent astronomical telescope with no external mechanical levers, integrated full-function optical components, a built-in automatic star-finding platform, high intelligence, no need for any external accessories, and a built-in astronomical camera. This would solve the problems of cumbersome operation, poor sealing, easy optical axis misalignment, poor image quality, and low intelligence of existing equipment. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings and deficiencies in the prior art and provide an astronomical telescope, comprising: a telescope body, a low dispersion objective lens group disposed within the telescope body, an imaging lens group, a visual module and a focusing mechanism, and further comprising a visual optical path switching structure and a control mechanism;

[0010] The imaging lens group includes an electrically controlled built-in extension module, an electrically controlled filter switching module, a planar field lens switching module, an electrically controlled focal reduction lens switching module, and an imaging module arranged along the optical path passing through the imaging lens group.

[0011] The visual optical path switching structure includes a movable reflector and a first rotating assembly; the movable reflector is connected to the first rotating assembly.

[0012] The control mechanism includes an external intelligent control module and a built-in main control unit disposed within the lens barrel body; the external intelligent control module is communicatively connected to the built-in main control unit, and the built-in main control unit is used to control the electronically controlled built-in extension module, the electronically controlled filter switching module, the electronically controlled reduction lens switching module, and the first rotating component;

It also controls the electronically controlled built-in extension lens module to switch the extension lens in the light path, controls the electronically controlled filter switching module to switch the filter in the light path, and controls the electronically controlled focal reduction lens switching module to switch the filter and focal reduction lens in the light path. When the light path is oriented towards the imaging lens group, the imaging module forms an image according to the imaging parameters corresponding to the one-key control signal.

[0015] The built-in main control unit controls the first rotating component to rotate the movable reflector, so that the movable reflector reaches a preset position in the optical path between the low dispersion objective lens group and the imaging lens group, so as to reflect the light in the optical path to the visual module through the movable reflector.

[0016] As one implementation, the step of the built-in main control unit controlling the first rotating component to rotate the movable reflector to adjust the optical path direction, so that the optical path faces the imaging lens group or the visual module, according to the one-key control signal issued by the external intelligent control module, includes:

[0017] The built-in main control unit controls the first rotating component to rotate the movable mirror, so that the first rotating component rotates the movable mirror away from the optical path between the low dispersion objective lens group and the imaging lens group, so that the light on the optical path is directed towards the imaging lens group.

[0018] In one embodiment, the electronically controlled built-in extension module includes an extension lens and a second rotating assembly; the extension lens is connected to the second rotating assembly, and the second rotating assembly is communicatively connected to the built-in main control unit; the built-in main control unit controls the second rotating assembly to rotate the extension lens according to the control signal issued by the external intelligent control module, so that the extension lens enters or leaves the optical path passing through the imaging lens group.

[0019] In one embodiment, the electronically controlled filter switching module includes a filter disk and a third rotating assembly. The filter disk has an opening and multiple filters of different wavelengths. The filter disk is connected to the third rotating assembly, which is communicatively connected to the built-in main control unit.

[0022] In one implementation, the low-dispersion objective lens group is used to suppress fundamental chromatic aberration and, in conjunction with the planar field lens switching module, achieves a dual achromatic effect, further improving the consistency of image color.

[0023] In one implementation, the lenses of the electronically controlled built-in extension focus module and the electronically controlled focal reduction lens switching module are both made of high-transparency optical glass, and the lens surface is coated with a high-transparency anti-reflection film to reduce light reflection loss and improve light intake and image clarity.

[0024] As one implementation method, the imaging module has a built-in image preprocessing module integrated with an astronomical camera, which is used to perform real-time noise reduction and sharpening processing on the captured celestial images. The processed images are then wirelessly transmitted to the target display device, enabling instant viewing after capture.

[0042] Please see Figure 1 This is a schematic diagram of an intelligent astronomical telescope according to an embodiment of the present invention, including a telescope body 1 and a low-dispersion objective lens group disposed within the telescope body 1. Figure 1 The objective lens 2), imaging lens group, visual module 9 and focusing mechanism, as well as visual optical path switching structure 8 and control mechanism.

[0043] The main body of the telescope tube 1 is made of lightweight material. To shorten its length, several fixed mirrors can be used inside the main body to change the light path, thus achieving a compact structure while maintaining optical performance. The inner wall of the main body of the telescope tube 1 is coated with a black anti-reflective coating to reduce light reflection loss. The main body of the telescope tube 1 can be fixed to the bearing end of a single-arm automatic star finder. The bottom of the single-arm automatic star finder is fixedly connected to the standard tripod, providing stable support and smooth operation.

[0044] The single-arm automatic star-finding platform features a lightweight, high-precision single-arm structure, a high-precision encoder, and a star-finding control unit. It can achieve synchronous tracking of celestial bodies at the equator, automatic star finding across the entire sky, and one-click positioning and locking of target celestial bodies. It is suitable for deep-sky long-exposure photography and high-magnification planetary tracking observation. The platform operates smoothly without shaking or backlash, perfectly meeting the stable observation requirements of the entire focal length range of the entire system. The standard tripod provides stable support when deployed and is portable and easy to carry when folded, making it suitable for outdoor observation scenarios.

[0045] The imaging lens group includes an electrically controlled built-in extension focus module 7, an electrically controlled filter switching module 6, a planar field lens switching module, an electrically controlled focal reduction lens switching module, and an imaging module 4, which are arranged along the optical path passing through the imaging lens group.

[0046] Specifically, the imaging lens group is fully sealed and integrated into the main body 1 of the lens tube. The imaging module 4 is an astronomical camera, which is fixedly built into the main body 1 of the lens tube and arranged coaxially with the optical path of the imaging lens group. The imaging end integrates an image preprocessing chip and a WiFi wireless transmission module, which can perform real-time noise reduction and sharpening processing on the captured celestial images and transmit the images to the control handle or mobile terminals such as mobile phones and tablets in real time, so as to realize real-time preview, editing and sharing.

[0047] The visual module 9 includes a zoom eyepiece and a 90° zenith mirror, allowing users to observe comfortably.

[0048] Please see Figure 2 The visual optical path switching structure 8 includes a movable reflector and a first rotating assembly; the movable reflector is connected to the first rotating assembly; wherein, the first rotating assembly can change the position of the movable reflector by a motor and reset it by a torsion spring.

[0049] The control mechanism includes an external intelligent control module 3 and a built-in main control unit disposed within the lens barrel body 1; the external intelligent control module 3 is communicatively connected to the built-in main control unit, and the built-in main control unit is used to control the electronically controlled built-in extension module 7, the electronically controlled filter switching module 6, the electronically controlled reduction lens switching module, and the first rotating component;

[0050] The built-in main control unit controls the first rotating component to rotate the movable reflector to adjust the direction of the light path according to the one-key control signal issued by the external intelligent control module 3, so that the light path is oriented towards the imaging lens group or the visual module 9. It also controls the electronically controlled built-in extension lens module 7 to switch the extension lens in the light path, controls the electronically controlled filter switching module 6 to switch the filter in the light path, and controls the electronically controlled focal reduction lens switching module to switch the filter and focal reduction lens in the light path. When the light path is oriented towards the imaging lens group, the imaging module 4 forms an image according to the imaging parameters corresponding to the one-key control signal.

[0051] The control mechanism is the core control unit of the entire machine, including an external intelligent control module 3 and a built-in main control unit located within the main body 1 of the lens barrel. The external intelligent control module 3 can be connected to the built-in main control unit via a wired data cable or wirelessly. The external intelligent control module 3 also has built-in WiFi and Bluetooth modules, allowing direct connection to mobile terminals such as smartphones and tablets, and can be fully controlled via a dedicated control APP. Except for manual fine-tuning and focusing in visual mode, all functions of the entire machine are operated electronically with a single button, without any external mechanical levers. This includes: electronic switching between imaging / visual modes, switching in / out of focal reduction lenses, switching in / out of tethering lenses, electronic switching of filter settings, start / stop of the field-level function, automatic star finding, tracking, and speed adjustment of the single-arm automatic star finder. The external intelligent control module 3's high-definition display screen can show all working parameters of the telescope in real time, including the current working mode (imaging / visual), focal length parameters, filter settings, field-planing function status, star-finding and tracking status, and battery level. Users can view and control these parameters with a single click, eliminating the need for manual adjustment of mechanical parts. Operation is extremely simple and highly accurate. The external intelligent control module 3 also integrates a unified power management unit, supporting both charging and battery power. This unified power supply adapts to outdoor observation scenarios, enhancing the device's portability and practicality. Specifically, the external intelligent control module 3 is a hardware device with a corresponding control program for the built-in main control unit, such as a mobile terminal or an integrated control handle with a built-in high-definition display screen.

[0052] In a feasible embodiment, the step of the built-in main control unit controlling the first rotating component to rotate the movable reflector to adjust the optical path direction, so that the optical path faces the imaging lens group or the visual module 9, according to the one-key control signal issued by the external intelligent control module 3, includes:

[0053] The built-in main control unit controls the first rotating component to rotate the movable reflector, so that the movable reflector reaches a preset position in the optical path between the low dispersion objective lens group and the imaging lens group, so as to reflect the light in the optical path to the visual module 9 through the movable reflector.

[0054] In a feasible embodiment, the step of the built-in main control unit controlling the first rotating component to rotate the movable reflector to adjust the optical path direction, so that the optical path faces the imaging lens group or the visual module 9, according to the one-key control signal issued by the external intelligent control module 3, includes:

[0055] The built-in main control unit controls the first rotating component to rotate the movable mirror, so that the first rotating component rotates the movable mirror away from the optical path between the low dispersion objective lens group and the imaging lens group, so that the light on the optical path is directed towards the imaging lens group.

[0056] Please see Figure 3In one feasible embodiment, the electronically controlled built-in extension module 7 includes an extension lens and a second rotating assembly; the extension lens is connected to the second rotating assembly, and the second rotating assembly is communicatively connected to the built-in main control unit. The built-in main control unit controls the second rotating assembly to rotate the extension lens according to the control signal issued by the external intelligent control module 3, causing the extension lens to enter or leave the optical path passing through the imaging lens group. The second rotating assembly may be a miniature motor.

[0057] The electronically controlled focal reducer switching module includes several focal reducers with different focal lengths and translation components; the translation components are communicatively connected to the built-in main control unit, and the built-in main control unit controls the translation components to drive the focal reducers of the target focal length to translate into or out of the optical path passing through the imaging lens group according to the control signal issued by the external intelligent control module 3.

[0058] The electronically controlled built-in extension lens module 7 and the electronically controlled focal reduction lens switching module are fully sealed independent optical modules. Responding to the electronic control signals output by the built-in main control unit, they precisely drive the lens to enter or exit the optical path without any external mechanical levers, exposed moving parts, or compromise the lens barrel's seal. The extension lens is made of high-transparency optical glass with a high-transparency anti-reflection coating on its surface, reducing light reflection loss and increasing light intake and image clarity. After electronically entering the optical path, the original focal length can be reduced to create a wide-field mode, significantly expanding the field of view. This is specifically designed for wide-area observation and long-exposure photography of deep-sky objects such as nebulae, galaxies, and star clusters, capturing a broader cosmic panorama. The built-in electrically controlled extension lens assembly also uses high-transmittance optical glass, with an anti-reflective coating on the lens surface. After being electrically controlled to enter the optical path, it can extend the original focal length to achieve high magnification, making it suitable for detailed observation and photography of close-range celestial objects such as lunar craters and planetary surface textures, clearly revealing the subtle structures of celestial surfaces. When the electrically controlled built-in extension module 7 and the electrically controlled focal reduction lens switching module are simultaneously electrically controlled to exit the optical path, the entire device maintains its original standard focal length, suitable for routine star field observation, daily visual observation, and other scenarios, meeting diverse observation needs of users.

[0059] Please see Figure 4In one feasible embodiment, the planar field lens switching module includes a planar lens and a mounting base. The planar lens surface is coated with a high-transmittance anti-reflection film, which can reduce light reflection loss and effectively correct field curvature, ensuring consistent sharpness at the center and edges of the image. The mounting base is sealed and fixed to the inner wall of the main body 1 of the telescope tube, ensuring the stability of the planar lens position and preventing it from shifting due to vibration, which would affect the correction effect. The planar lens assembly participates in the optical path throughout all focal lengths, correcting field curvature, edge distortion, and axial and lateral chromatic aberration in real time. When used in conjunction with the low-dispersion objective lens group, it achieves a "double achromatic" effect, significantly improving image quality and solving the defects of blurred edges and color distortion in existing telescope images. This results in clearer and more accurate astronomical images, reaching a professional level for entry-level astrophotography.

[0060] Please see Figure 5 In one feasible embodiment, the electrically controlled filter switching module 6 is completely coaxial with the optical path of the imaging lens group, without affecting the light transmission and imaging quality. This component includes a filter disk and a third rotating assembly; the filter disk has an opening and multiple filters of different wavelengths. The filter disk is connected to the third rotating assembly, which is communicatively connected to the built-in main control unit. The built-in main control unit controls the third rotating assembly to rotate the filter disk according to the control signal issued by the external intelligent control module 3, causing the filter with the opening or target wavelength to enter or leave the optical path of the imaging lens group.

[0061] Specifically, the electronically controlled filter switching module 6 includes a miniature rotary drive motor, a high-precision positioning structure, multiple astronomical-specific filters, and one open / clear position (i.e., the opening). It uses an electronically controlled signal to drive a turntable for precise rotation and positioning, enabling one-button switching between multiple positions. The switching process is silent, precise, and seamless, with the entire telescope tube sealed. No parts need to be disassembled, observations are not interrupted, dust cannot enter, and the optical axis remains unchanged, completely solving all the shortcomings of traditional manual filter disassembly and external lever filter structures. The filters are configured to suit common astronomical observation scenarios. No filter intervention occurs during open / clear position switching, maintaining full-spectrum light transmission. It is suitable for conventional broad-spectrum observation and photography, and can quickly adapt to different scenarios such as urban light pollution environments, deep-sky broad-spectrum photography, and high-detail planetary observation.

[0062] In one feasible embodiment, the low-dispersion objective lens group is used to suppress fundamental chromatic aberration and, together with the planar field lens switching module, achieves a dual achromatic effect, further improving the consistency of image color.

[0063] In one feasible embodiment, the imaging module 4 has a built-in astronomical camera integrated image preprocessing module for real-time noise reduction and sharpening of captured celestial images. The processed images are wirelessly transmitted to the target display device for instant viewing.

[0064] The usage process of this embodiment:

[0065] 1. Installation and debugging: Unfold and fix the standard tripod, fix the single-arm automatic star finder to the top of the tripod, fix the main body 1 of the telescope tube to the bearing end of the single-arm automatic star finder, connect the power supply, and complete the equipment initialization and polar axis calibration through the control handle or mobile terminal to enter the working state.

[0066] 2. Visual observation operation: Switch to visual mode with one click using the control handle or mobile terminal, and drive the reflector to rotate to the center of the optical path; locate the target celestial body with one click using the single-arm automatic star finder; after positioning, perform smooth and precise focusing by manually fine-tuning the focusing mechanism until the celestial body image in the eyepiece is clear, and then you can perform visual observation.

[0067] 3. Astronomical Photography Operation: With a single button, the system electronically switches to imaging mode via the control handle or mobile terminal. The electronically controlled mirror rotates to a clearing position, allowing direct light path to the built-in astronomical camera. A single button selects the corresponding focal length: for deep-sky nebula photography, it switches to a reduced-focus full-frame wide-angle mode with the corresponding deep-sky filter; for regular astronomical photography, it uses the native focal length; for planetary and lunar surface photography, it switches to a high-magnification focal length mode with the planetary enhancement filter. A single-arm automatic star finder enables astronomical synchronous tracking, ensuring stable long-exposure photography. Images captured by the built-in astronomical camera are pre-processed in real-time and wirelessly transmitted to the control handle or mobile terminal for real-time preview, storage, editing, and social media sharing. The entire process is electronically controlled, requiring no interruption of observation, no disassembly or assembly of accessories, and no external camera connection.

[0068] 4. Full-function adjustment: All focus switching, mode switching, filter switching, star finding and tracking, and field leveling function activation and deactivation can be completed with one click via the control handle display or mobile terminal, without touching any mechanical parts; only in visual mode can the manual fine-tuning focusing mechanism be used to achieve precise focusing, balancing intelligent convenience with professional observation feel; the display screen synchronously displays all working parameters in real time, allowing users to grasp the device status with one click and quickly adapt to all observation and shooting needs.

[0069] The intelligent astronomical telescope in this embodiment fully meets the design requirements of being completely sealed without external levers, having full electronic control function switching, precise manual fine-tuning, automatic star finding and tracking with a single arm, and an astronomical camera built into the imaging end. It integrates six core functions, has a compact structure, is extremely easy to operate, has a high degree of intelligence, excellent imaging quality, and strong scene adaptability. It can meet the astronomical observation and photography needs of all people and all scenarios, and completely solves all the technical defects of traditional telescopes, making it extremely practical.

All optical paths are coaxially aligned at the factory, eliminating the need for subsequent mechanical disassembly and ensuring stable and excellent image quality: All optical components (Objective 2, focal reducer, telephoto lens, filters, field planer, and built-in astronomical camera) undergo full coaxial alignment before leaving the factory. During use, there is no mechanical disassembly or external lever adjustment, permanently guaranteeing optical path stability and avoiding optical axis offset issues caused by external accessories or manual operation. The low-dispersion objective 2, in conjunction with the permanent field planer, achieves double achromatic correction, effectively correcting field curvature and edge distortion, ensuring simultaneous sharpness at the center and edges of the entire image, significantly improving image quality and meeting the needs of long-exposure astrophotography.

It is suitable for outdoor observation, science education, and indoor experiences. The built-in astronomical camera design eliminates the need to carry an external camera, further enhancing the portability of the device.

[0076] 6. Adaptable to all scenarios and highly practical: Three-level electronically controlled focal length, electronically controlled filter settings, dual control modes, automatic star finding and tracking, visual / imaging dual modes, built-in astronomical camera for shooting without external attachments, can meet the needs of astronomy enthusiasts for daily visual observation, deep sky photography, planetary detail shooting, long exposure photography, science popularization and teaching, etc., with a wide range of users and comprehensive performance far exceeding that of traditional telescopes of the same type.

[0077] As a feasible implementation method, the module information included in the intelligent astronomical telescope of this application is as follows:

[0078] 1. Optical module

[0079] 1.1, Diameter 80mm

[0080] 1.2. Built-in 2X magnification system: The motor drives the 2X lens group to rotate 90 degrees to achieve 2x magnification; otherwise, there is no change in focal length. This operation requires an app.

[0081] 1.3. It comes with a built-in 4-aperture filter dial (digits 0, 1, 2, and 3), controlled by a motor. Normally, it is in position 0 (empty). Rotating it 90 degrees clockwise activates digit 1 (filter), 90 degrees counter-clockwise activates digit 3, and 180 degrees counter-clockwise activates digit 2. These actions require app operation.

[0082] 1.4. A specially designed visual observation function, which is the characteristic of traditional astronomical telescopes observing through the eyepiece. This tradition is retained because several currently available smart astronomical telescopes produce poor results when photographing planets, failing to capture planetary features such as Jupiter's Great Red Spot, Saturn's rings, and Mars' polar ice caps. The human eye provides the highest resolution. This step requires adjusting the camera module (described below) to a specific position to achieve visual observation, which is accomplished through the app.

[0083] 2. Camera photo module

[0084] 2.1 Built-in camera, motor driven. This action requires APP operation to move the camera module forward or backward. The camera software needs to be able to automatically identify the objects being photographed (ground targets) or objects at infinity, such as the moon, Jupiter, stars, or even nebulae at their maximum intensity or other maximum values, and communicate with the module driving the camera to automatically notify the camera motor to move forward, backward, or stop.

[0085] 2.2. Camera Functions: Photography and video recording. The camera should have automatic and manual adjustment modes, such as exposure time and gain, to enable it to adapt to low-light environments when shooting the moon, planets, and nebulae, producing high-resolution images.

[0086] 2.3 The camera can automatically process and overlay images or videos, storing the photos in the camera's memory. They can also be transferred to a mobile app for viewing and social sharing via Wi-Fi / Bluetooth.

[0087] 2.4 Outlook: The original photos taken by this camera can be uploaded to the cloud, where the powerful processing capabilities of the server can help users process massive amounts of image data and obtain a better image experience.

[0088] 2.5 Camera Functions and AI Interaction: Experience more information and dynamics of the shooting target through AI, and develop in sync with the development of AI.

[0089] 3. Automatic satellite finding and tracking module

[0090] 3.1 Platform (commonly known as bracket): This is a horizontal or ground-level system. This part is already completed. It includes the motor and mechanical transmission structure for horizontal and vertical movement.

[0091] 3.2 The test bench includes a 9-axis gyroscope sensor and an electronic compass sensor, which are required for intelligent operation, serving as the basic coordinate system.

[0092] 3.3. Simultaneously, there is an algorithm to improve the accuracy of the basic coordinates.

[0093] 3.4 The test platform includes a Wi-Fi / Bluetooth module, enabling bidirectional communication with a mobile app. The app sends target commands, which are transmitted to the platform's Wi-Fi / Bluetooth network via the phone. Simultaneously, the platform's coordinates can be transmitted to the app in real-time when needed. Once a target is found, the platform automatically enters target tracking mode, awaiting the user's next command via the app, such as finding the next target or taking a picture.

[0094] 4. APP

[0095] 4.1 This phone's apps involve Android, iOS, and HarmonyOS systems.

[0096] 4.2 This APP is not just an application, but also communicates with the physical layer (the two motors on the platform, the three motors inside the astronomical telescope, and the camera).

[0097] 4.3 The app is a virtual planetarium with a database, calculations, graphical representations of constellations, and a chart showing the position and phases of a target object throughout the year in different months and dates. For example, it shows the phases of the moon from the first quarter to the full moon and then to the last quarter; or the angles of Saturn's rings. All of these are time-related.

[0098] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, and variations made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
