Embodiment approach

[0027] according to Figure 1-4 The first embodiment of the present invention is shown. The telescope of the present invention that can be attached with an external guide star device includes a telescopic objective lens group TL and a guide star lens group GSL. The telescopic objective lens group TL and the guide star lens group GSL pass through The anti-semi-transparent beam splitter 102 shares the same eyepiece group 101 . Wherein the telescopic objective lens group TL includes, from the observer side to the object side (for example, the side of the starry sky to be observed), the first converging lens 107, the second converging lens 108, and the telescopic collimating objective lens 109 arranged in sequence, wherein the first A converging lens 107 and a second converging lens 108 form a relay lens group, using double cemented spherical lenses; the guide star mirror group includes, from the observer side outwards, the third converging lens 103 arranged in sequence, reflector...

Abstract

The invention relates to a telescope with an attached external guiding device. The telescope comprises a telescope objective lens group and a guiding lens group. The telescope objective lens group and the guiding lens group share the same eyepiece group through a spectroscope. The guiding lens group can help satellite observation software in portable intelligent terminals such as a smartphone to carry out visualized multimedia information guiding on the starry sky observed by the current telescope. Compared with a traditional astronomical telescope, the telescope provided by the invention has the advantages that a fused image formed by a finderscope lens group and the telescope objective lens group is acquired at the pupil exit, so that a primary astronomy enthusiast can conveniently use the telescope.

Description

technical field [0001] The present invention relates to a telescope that can be attached with an external guide star device, in particular, relates to a telescope that utilizes a portable terminal to guide astronomical observation. The multimedia application running in the portable terminal is combined with optical elements to realize real-time fusion of multimedia images during starry sky observation It is displayed on the astronomical telescope to realize auxiliary star observation. Background technique [0002] For teenagers and junior astronomy enthusiasts, it is difficult to simply use astronomical telescopes to observe the starry sky and find a certain star or a certain constellation in the starry sky. Because looking for stars and observing constellations requires a lot of professional astronomical knowledge. [0003] In order to solve the problem of finding stars, astronomical telescopes are generally equipped with finder mirrors to find the target star point. Howev...
