Hi Dave,
Do you know why the bright stars have a magenta and/or blue flare in the 5 o'clock position? Does your scope have field corrector installed?
The detail in the main object came out really well but I think the colour balance of the brighter stars is off, far too much orange. Perhaps due to trying to incorporate Ha, have you tried just RGB or LRGB to compare?
From a dark sky site the advantage of Ha on broad band sources (e.g. galaxies) is marginal, yes there are emission nebula in there but they are compact plus relatively bright, and the R filter can usually do a good job of isolating them. On galaxies with faint emission jets (M82 being the best example) the Ha can help out.
You mentioned binning 2x2, was that also the case in L? I think for the 8300 sensor it would be better to image L at 1x1 with subs long enough to overcome read noise. The CCD dynamic range is usually more compromised when binning due to the limited well depth of the read out register. I don't know what the hit is in 2x2 for an 8300, you could measure it by looking at the ADU count where a star flattop's.
Best,
EB
