Thanks Edward. Yeah 3.5 pixels I believe is what NINA reports, that translates into 6-7 arc seconds (2.18 as/px scale)
Many people report getting 2-3 arc/sec which seems not achievable to me
That link is actually a 10 minute sub from my target. I dont think NINA saves the images it takes for AF (at least not that I know of)
This is a Nikon D5300 for the imaging camera
Without the duo-band filter, I can get into the high 2 "pixel" scale but it was still 5+ arc seconds which just seems huge - many people report tossing *any* sub over 4" for instance ... very odd
My skies are not great (Bortle 6 but also feel very "milky" for want of a better word
