Getting a closer look at the Moon isn’t difficult; even a complete novice can aim a low-cost telescope at our closest celestial neighbor and get some spectacular views. However, if you want to go a little deeper into the black, and particularly if you want to photograph what you find, things can quickly become complicated (and expensive).
Although building this 3D printed automated telescope built by [Greg Holloway] isn’t inexpensive, particularly when you consider how much your time is worth, the final product appears to be much more streamlined than most commercially available options. Instead of lugging around a separate telescope, tripod, motorized tracker, and camera, all you need is this relatively small all-in-one unit.
[Greg] spent six months building his miniature observatory, and it shows. The CAD job, as well as the documentation in general, is outstanding. Even if you’re not interested in peering into the heavens, taking a look at this project’s Instructables page is well worth your time. There’s something for everyone, from his advice on designing for 3D printing to detail on choosing the right lens and pairing it with the Raspberry Pi HQ Camera.

The star tracker is one of the most promising optical attitude measurement instruments, and because of its high precision, it is commonly used in spacecraft. However, until now, how to realize and check such accuracy has remained a critical but unresolved problem. The accuracy measurement method used by a star tracker will ultimately decide the satellite’s success. This paper proposes a new and robust precision measurement approach for a star tracker based on direct astronomical observation. In contrast to the traditional approach, which uses virtual stars as observation targets, this method uses actual navigation stars as observation targets, resulting in more authoritative and authentic measurement results. On the basis of the precision motions of the Earth, transformations between various coordinate systems are carried out, and error curves of directional vectors are obtained along the three axes. This paper proposes a three-axis accuracy measurement criterion based on error analysis and accuracy concepts, which can explicitly ascertain the pointing and rolling accuracy of a star tracker. Experiments have shown that this approach is both efficient and simple to implement. This type of measurement setting is similar to in-orbit conditions and can meet the stringent requirements for high-accuracy star trackers.
