One of the things I desperately want to do is take Hubble-quality photographs of the stars. Unfortunately, i don't have several billion dollars worth of camera, telemetry, and rocket equipment at my disposal. But I do have some cheap cameras,  some telescopes, and a little bit of time, so let's get started. 

The easiest thing I can think of doing is hold up my camera to the lens. This does work, if you have steady hands and a camera that understands what is happening, but mine kinda...

Don't really... 

So, scrapping this idea, at least temporarily, as the moon pictures above can show, this camera is capable of taking some decent shots, so long as the optics are lined up properly. But the other realm i have access to is the Raspberry Pi, and its 5MP camera. There are models galore out there for those who wish to use a full-size Pi on the end of their lens. I however, do not. 

My solution is simple: Use a Zero. Smaller & lighter has always been the preferred method for space-fairing computers, so why should the terrestrial versions be any different? I started by hunting down some camera-to-lens adapter 3D models. while there were a couple of ones I could salvage off of the "mount the whole Pi to the lens" style, I found this lens adapter that at first glance seemed to really be a good choice. I printed it out and broke out one of my telescope lenses. 

Well that's an issue. The model was probably designed for use in the smaller 1" eye pieces commonly found on smaller, less expensive refractor telescopes. A quick test with one of my refractor lenses revealed some interesting results:

Still, I needed to model a lid for my Newtonian Reflector. I mirrored the dimensions for the base and took some dimensions off of the dust cap I modeled and printed for replacements.
