Equipment

Meade 16in LX200 telescope operating at f/10

SBIG ST8E CCD camera with color filter wheel

LRGB color production was used to create this image.

The AO-7 was used to acquire this image.

Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image.

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 = 80 minutes binned 1x1

Red = 30 minutes binned 2x2

Green = 30 minutes binned 2x2

Blue = 60 minutes binned 2x2
