This Galaxy season I decided to try to fine tune my OAG setup. This year I would also replace the ZWO Mini filter wheel with the Starizona Filter Drawer which can handle 2″ filters. In this video I show the transition to the Starizona and the final configuration that now utilizes the v2 Large SCT Adapter by Celestron which actually allows hitting that 146.05mm target backfocus pretty close.
I also outline my steps I am using to calculate focuser backlash and how to enter those settings in NINA.
