Description

M82 (Pure, Deep and Final)

I had an idea for one more M82 version...

PURE because I use a Lighten blend of Ha over RGB. I believe this preserves the RGB much more than a screen blend.

DEEP because I use 20 hours of Ha in a 21.3 SQM sky.

FINAL because I promise this is the last version – at least for 2020. (-:

The layering technique used here is...

Ha(Screen)L - Ha(Lighten)RGB.

Here's all the previous versions for quick reference...

M82 5 hours

M82 13.8 hours

M82 43 hours with Adam Block 32" Ha in moonlit sky

M82 35 hours with KG 24" Ha in 21.3 SQM sky
