Hi Slawomir,
Those values are indeed in arcseconds, as taken directly from PixInsight's SubFrameSelector script's output. I make use of Drizzle on my binned RGB data. It has worked incredibly well for me!
Hi Ray,
Thanks for the explanation! I understand that I'm heavily undersampled at 3.5"/pixel. Even if it's not a truly useful measure in my case, do the values I've quoted (which are actually quite typical, across my data) mean that I have reasonable seeing in my location? Mind you, I only image between 45 degrees either side of zenith. This isn't even in my control, as I've specifically told my automation software to only image between those altitudes.
