I took a stab at bringing out the dust surrounding the Pleiades in my December 2018 capture. I had no idea the dust was so bright—this is just 10 minutes at f/2.8 (whereas it took 4 hours at f/2.8 to bring out the same amount around the Blue Horsehead):

Thanks asanmax. This was at the top of the light dome to my north, which is at ~Bortle 4.

Thanks, just wanted to get a reference point as I typically image from Bortle 8 zone. Quite impressive for a 10 min integration.

That's just 2.8× the flux integral of what I got. So not much more needed at all.

Hi BQ

This is from 4 years ago with my CGEM and HD 11 and modded Canon 40D. I think it was about 30 or 40 minutes integration time but I don't remember exactly. Processed it with StarTools.
