The Dumbbell Nebula

Spent one night for OIII and one night for Ha. RGB was shot in the third night.
I played a lot with NBRGB Combine (strechted, non strechted), Forax, etc...

At the End I used the RGB Stars and screened them back to the NBRGB Image.
I don't know how the image solver "found" M55 in this picture ?!?
