The galaxy Messier missed...

Link to the website with full details.

It came out better than I had hoped for with "just" 3h15m of data.

I compared my result with the recent version of Yfronto/Mike. His result and colours are excellent! I had trouble with the blues. There was a lot of magenta at the end of my processing.

Great result Maurice.

I found ha data helped a lot with the colour in my shot.

Lovely image, Maurice. I was surprised to read that there is no Ha in this because it has lots of crisp little highlights that I assumed were Ha when I saw it. Glorious star colours as well. A quality product!

That is a nice image, sharp and I like the colour. I know from experience how difficult this one is, my attempt last month failed due to weather. Congrats on a good image
