very nice images Asi.
FWIW re histo, I use 30HzRG + 15HzB at about f28 at full gain and whatever histo that yields. adjust colour levels to pre-determined calibration ratios using multiplication function in IRIS before combining and sharpening. Final colour tweak in GIMP to get neutral grey rings and I normally try not to interfere with linear image value relationship (no non-linear curves adjustment and no gamma adjustment anywhere in the process) - unless needed to bring out a specific feature such as a storm spot. Alternative approach is to use about f20 at 60/30hz and super-res drizzle to recover resolution if fine detail is there, but local seeing will not support 30Hz - but this results in larger files and more read noise.
re dust, a routine cotton bud clean (or two) before each session.
