So I have been working today on the Veloce, and can tell you some good news:
- The tilt and collimation were sort of interconnected. While not completely resolved, the situation has much imroved. In bin 2x2 stars are round across the field. In Bin 1x1, they mostly are, but some finetuning is needed. Not exactly easy as the needed corrections are in the order of 1/32th of a turn or less 😅
- Changed the O3 filter, new one is a Astrodon 5nm one
- Removed the S2 filter, swapped with a Dark filter
- Disabled the overscan areas.
So, please use the new calibration data that I will gradually collect over the next days. With the new darks the data quality will improve by a huge margin, too 😀
