This is my first season of imaging galaxies, as I started about NEAF time last year.
I have tried to stay away from LRGB imaging because of the heavy light pollution in my city.
I think about going to a dark site, but I am too comfortable at home and I keep my rig outside almost permanently and don't want to move it.
A couple of weeks ago I imaged the markarian chain at gain 200 without really thinking about it too deeply.
My darks were all for gain 200, so that is what I did.
My Lums were at 4 seconds and at the other end red was 45 seconds.
Processing out the LP in Pixinsight was pretty hard and I felt like I just needed to leave a certain amount in the image in order to not degrade the resolution.
THis week I took a bunch of darks and biases and made masters at unity gain and at gain 75.
What I am wondering and hoping to get out of this post are ideas on the best gain settings to use that would possibly minimize the impact of LP, if that is even possible.
I would love to also hear about techniques for processing that people use that image RGB in a heavy light pollution environment.
