First time trying 5 min Luminance subs and I will NOT be going back... I shouldn't have stuck with 2 min subs for so long.
This is a fairly bright galaxy and has some cool neighbors nearby.
Open in desktop to see all the smol guys.

Stunning

I love that you can see the plane of the galaxy is curved

I currently do 2 minute subs. What's the main benefit you're getting? Why would you want to risk a satellite ruining 5 minutes?

Much more signal
Of course stacking is just a trick, what we really want is to get that sensor exposed for as long as possible.
Also 80% of sats get rejected

Really? I wouldn't have thought the signal increase meaningfully from 2 min to 5 if you're in broadband under b5/6
and relatively low read noise camera

B5/6 with no moon takes very nicely to 5 min L subs.
And definitely on RGB as they are generally darker.

It's definitively better but I wonder how much in practice (in theory, with the sky luminosity evenly spread over the visible spectrum, i calculated a 0.4% improvement for rgb)
Oh and beautiful image btw !

Well my comparisons between 2 min and 5 min L subs on this same galaxy were very noticeable
I'll send them here later when I get to my computer.

nice, real world data

Yep, I find that usually tells a very different story than what's on paper (there are exceptions of course).
night hatch
Indeed, every couple subs.

Sorry I wanted to ask drizzle 😅
night hatch
Ahh lol
Nah I don't drizzle
My pixel scale along with my average seeing conditions would never take advantage of it
lavish abyss
I still prefer it for the nicer noise profile but i guess it's not much of an issue when you don't have to debayer
