Thanks everyone for your observations and suggestions.
Mike, the collimation was way off, just lazy due to test.
I'll post my other Cone image today, Andy noticed my seagulls. The cam is full frame but I fear my RCC1 corrector is not up to the task at the edges. No matter, a bit of cropping can help. I think as it has 91mm backfocus, it can't possibly do well at the extremes? I never had such probs with my Tak.
I also see the long image train and connections have a bit of play in them, so sensor tilt won't help.and every time I rotate the cam it'll change.
Louie, I will be doing 5 min subs on this soon I hope, getting real detail and colours is the big test!
Thanks COLIN, I'm hoping the combo works well. It is great for RUB but I feel noise is too high being uncooled. Maybe doubling subs or dithering might help?
Marc, Thanks, and I'm in the beta program for ASCOM for this camera. But sadly you need to upgrade firmware to 3.2 meaning I would get the dreaded star eater feature after 30sec. Will need to test 30 sec subs....
Alan, I have a Howie glatter laser and tublug, so when I actually spend the time, coll is pretty good. But coma at edges is bad as noted.
What I need to do soon is compare efficiency to my asi1600, then hopefully just use the 1600 that supports elec focusing so much better
