Re: Image - early Sharpless 2 processing

Nicely done!  Focus does look a bit soft when you zoom all the way in. Unsure if that's because of dew, seeing, or if focus is off.  Did you do a focusing run between each filter change?  Even the Astrodon's aren't quite parfocal, although they're about as close as you're going to get.  The halos are uniform so I don't think it's collimation.

I have a PixInsight routine for getting rid of star halos.  I'll dig it out if you're interested.
