LRGB color production was used to create this image.

Instead of trying to image both targets individually, the choice was made to try to squeeze them into the same

frame. This was very difficult due to the guide star and the size of the field of view.

Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of

the image simultaneously.

Luminance = 105 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
