Celestron SCT 8 or C8 focuser braket
thingiverse
I designed this nema 17 bracket for my SCT8 so I can have autofocus. The system is mounted to the Celestron 0.63 reducer. Motor braket and telescope fixture can be printed in PETG I suggest the nema 17 coupler in TPU filament so that misalignment can be absorbed. I'm controlling the autofocusing process using one of the focuser outputs of my onset converted CGE Pro mount (https://onstep.groups.io/g/main/wiki/3860), but almost any stepper motor control can work with it, for example ardufocus https://ardufocus.com.
