Hi Mike,
you have done well - a magnificent result for your first light picture.
I don't think anyone else here is getting such good FWHM figures?
Your frame that I checked was a Luminance frame.
I always found that the L frames were always slightly worse than any RGB frames
and that Ha frames gave the best FWHM.
e.g.
if an L frame was 3.3 arc seconds an Ha frame might be 3.0 arc seconds.
therefore your values could be a bit better with RGB or Ha frames -
maybe as low as 1.5 arc seconds?
cheers
Allan
