Description

I'm very proud of this image! It was an audacious project, took me a lot of patience, nights and discarded frames, but at the end, it looks better than I've expected! I've tried to make the most natural processing possible. This was also my first guided shot with the Meade ETX60 and the svbony sv105. I can say that the EQ3-2 works fine, but it does have eventual huge errors in the DEC axis. Stars were a bit bloated because of focusing issues, so I've reduced them. I was also mesmerized by the amount of hydrogen alpha nebulosity captured with a stock DSLR.

If you have any constructive criticism, please let it in the comments- having a second opinion is always the best for next processing sessions.
