Focuser support for Celestron C5

thingiverse

This is a support for a step motor (28BYJ-48) to focus on Celestron C5 scope. It comes in 4 parts: - The support - The motor case - The gear - The shaft cap You need some M3 bolts with nuts. 2 M3 (8mm) bolts with nuts in the gear. You put the nuts in the gear central hole and you screw the bolts in. They will be tight on the scope shaft. 2 M3 (30mm) bolts with washers and nuts to hold the motor. You need a small belt that you cut and glue at the right length. And I use a commercial gear for the motor. The cap covers the end of the scope shaft. Many arduino projects use step motor as electronic focuser. I used EQFocuser and I'm fully satisfied.
