Hi again David.
I managed a bit of semi clear sky last night and ran up the F7.5 80mm refractor with the ASI290MC just for fun.
It is apparent that, as you seemed to say, aperture rules here. I did a 10minute stack of 30second subs in RAW16 mode and … well it was disappointing really. I was imaging M16 - a good strong Ha source. I registered only a faint green luminosity with very little contrast or definition. OK. seeing wasn’t great but …
Also an issue, I could not stack subs of unequal length in DSS or access the SharpCap stacks in Photoshop - format not recognised.
Not the best start.
