Vingo, I can't explain why there is less amp glow, maybe coz it was colder, but the Neb is a bit fainter because I was imaging thru foggy haze last night with the filter. Transparency was miserable, whereas on the night I took the unfiltered image the sky was like glass.
I attempted 2 Galaxies (M83 & NGC4945) and they came out terrible, and the extra exposure time made the Amp glow show up just as much as without the filter. Even though the Galaxies were a failure, the stars around them still looked nice. Maybe the fog killed the Galaxies, dunno, but I'll try them again on a clear night.
