WOW!  That's a really fantastic M3 image.  I struggled imaging M3 early this month and I could never get an image that "popped."  Yours is really spectacular and it's exactly what I had in mind when I started my project...but I just couldn't pull it off.  Your colors are perfect and the stars look dazzling.  VERY well done!  This is how a good globular cluster image should look.  I am really impressed.  A+!

This is an excellent result, very well done!

 

Are you be able to provide the used settings of the ArcSinhStretch processtep?

Wow! Noodle, great job! I like that little arc of stars up along the top left edge of the image.

Outstanding processing too!

M3 sure does have a lot of galaxies in the background. Very nice!

Yep, that's what I used and I agree that it's a good tool for globulars.
