[APML] B86 and Red Halos

["Mario Cogo" <cogom@aruba.it>]

Matt,

Very good image.
This is a beautiful object, and your shot shows more details than mine,
in particular inside the dark region of B86.
The difference from AP130 with 67 and Traveler with 35mm is clearly visible.

I also noticed in my image some slightly red halos around the bright red
stars.
Yes, I known that it's a cropped area from the original Sagittarius Star
Cloud frame, but does anybody have any tips or Photoshop techniques
to reduce only the red halos?

Thanks
Ciao

gives you an idea of how much detail is there.
