Stepper Motor Mount for Celestron C11 Autofocuser

thingiverse

This mount allows attaching a NEMA 17 stepper motor with planetary gearbox directly to the CPC1100 or EDGE HD 1100 focus dial. A separate insert must be lightly pressed into the brass focuser barrel for precise fitting, leaving it up to you to fine-tune it for your specific motor and print requirements. This setup enables using Robert Brown's MyFocuser on SourceForge, a valuable tool for controlling focus in various settings. Its applications include observatory use, educational events where manual focus adjustments are restricted, and any other situation where precise focus is essential. Accurate planetary viewing or imaging heavily relies on proper focus, which can be compromised by mechanical vibrations caused by touching the scope during focusing. With Robert's software, you can seamlessly integrate this system into astronomy software or utilize it independently.
