These are the first images I took with my new setup. But I never took the time to process them.
The framing is done on purpose, to see all the dark clouds, called IFN (for Integrated Flux Nebula) and to show that the sky is never black when you expose long enough.
The Ha filter shows small nebula inside m81 as little red spot inside the galaxy.
my setup:
Telescop: FS60CB
Camera: ASI 2600MM
Several filters are used:
Ha: 3.5h
L: 4.2h
R: 1.6h
G: 1h
B: 1h
Have a good day.
Whoorrrr! Look at those galaxies, nebulas… 
Do you have a really dark sky?
Awesome. Where did you take this?
This is taken from my backyard.
I live in a small village near Dijon in France. The sky is not too bad even if you have to point in the right direction.
That’s even more impressive than I thought then! I’m really amazed.
Nice! For those exposure times - are those single exposures, or total time for a stack for shorter exposure times?
I’m thinking this might be a very useful test case as far as experiments/changes in color management.
This is multiple single exposures over several nights.
L: 126x120"
Ha: 42x300"
R: 48x120"
G: 30x120"
B: 30x120"
If I went out into my backyard at night and pointed my camera up at the sky, all I’d see would be a constant bank of rain clouds and a few insomniatic pigeons. 
I’ve also heard an outrageous claim that, during the day, the sky is blue — whenever I look up, it’s always grey! 
What an amazing image, @lock042! Well done!
