Description: More data added

Dusty Mountain BBW 56 in Hubble Palette with RGB stars.

This is now my most exposed tiny rectangle of sky:

Ha 30 x 600s
Oiiii 73 x 600s PLUS 26 x 900s
Sii 60 x 600s

33.7 hours of exposure, all at gain 200, offset 50

(Not counting the exposure for the stars, which would be lucky to be 2hrs).

Normally if I get over 20 x 600s in each channel, I'm happy.

This nebulosity in Puppis is super faint. At f/7.6 my image train is probably just too slow to expose this any better. I suppose I could start again with 30 minute subs!

Processing this today, I stumbled upon a new channel combination that made it easier to achieve a better Hubble Palette result I think.
