Excellent for an alt-az mount.

Indeed, a very good result from a Dob.

I'd watch your black point and be careful not to clip it. You might have more data in this capture than you think...

Thank you everybody for the comments guys

Olly thank you so much for your invaluable tip much appreciated  

I didn't touch the black point at all because the histogram was completely squashed on the left (i suppose it was underexposed).

I had to force a bit the background contrast because the target went to low and in the direction of that side of my house there is an annoying orange street lamp that reflect on the wall of the next house, so when i was stretching the pic this orange/yellowish shade was coming out all the time.

Often happen to me that the histogram is squashed on the left side, is there anyway to adjust this while shooting (is this related to bracketing?)?
