Well, I looked at the best of my videos from the other night, and
decided my stars are too soft for me to want to embarrass myself by
posting the M36 pic. One frame came out pretty nice, but it's got
that grainy multicolored sky background that makes me want to hurl my
lunch when I look at it.
You may want look at trying a LPR filter. It can at least knock the light pollution back some.
I never used it successfully with the MAK 127 because it had so little light gathering that exposure times became ridiculous.
With the C8 I want to try it again.
Also light pollution also affects the guider too. At a dark site, I guide off star that are say 1 to 2 magnitudes fainter than I can ever do in the city.
