Raspberry Pi HQ Camera to Celestron FirstScope adapter (With C-mount)

thingiverse

Can't find focus with your Raspberry Pi HQ Camera on your Celestron FirstScope (or similar)? Me neither, so I made this adapter that bolts to the camera instead of the stock C-mount and replaces the part in the FirstScope focus mechanism that has the set screws to retain the eyepieces. Result is that the camera screws directly into the focus mechanism, gaining 10-20mm of focus distance. This adapter removes the IR filter on the Pi camera, so if you don't want to shoot in IR too, you'll need to use the C-mount on the adapter to screw in a 1.25" adapter with IR filter.
