Stepper Motor Mount for Celestron C11 Autofocuser by jfrech14

Last crawled date: 4 years, 2 months ago

This mount allows you to attach a NEMA 17 stepper motor with planetary gearbox to a CPC1100 or EDGE HD 1100 focus dial. There is also an insert that must be lightly press-fit into the brass focuser barrel. This is excluded so that you can fine-tune it for your motor and print. This allows you to use Robert Brown's MyFocuser on SourceForge. This can be useful for controlling focus in observatories, at educational events (so that nobody touches the focus) or anything else. Focus is critical for planetary viewing/imaging. Touching the scope while focusing will always result in less accurate focus due to mechanical vibrations. With the software Robert provides, you can integrate it into astronomy software or use his.
