Description

This is my first image with my new setup.  (UNC25410, asi 2600mm)

Actually, as it is not fine tuned yet, I just wanted to center M81, an didn't really care about M82, as I had in mind to crop the image.
I was nicely suprised to see that M82 came out pretty well, and finally kept the inital framing.
Still a bit of tilt to deal with in the bottom left corner, but overall I'm really pleased with the result, it looks promising.


Sequence details:
191 x 40" L filter
30 x 60" R
30 x 60" G
30 x 60" B

I used NINA for the sequence.
