If you are interested in astrophotography and you want to make a low cost DIY setup here is a great project. Greg Holloway developed a Raspberry Pi Zero based wireless camera for a 1.25" telescope eyepiece receptacle with 3d printed casing. It is battery powered so you can take it in the wilderness to observe the stars.
