This adapter lets you connect a Raspberry Pi Camera to a telescope. There are two mounting options, one for inexpensive telescopes with 1" eyepieces and another for 1.25 " eyepieces that are common on more expensive models. I originally put this on an old Tasco refractor with a 1" eyepiece. Later, I added parts to mount to a Meade reflector with a 1.25" eyepiece.
The bracket holds a Pi Zero with a USB shield attached.

The design uses several pieces so that it can be printed without supports
