Meade 16in LX200 telescope operating at f/10

SBIG ST10ME CCD camera with color filter wheel

LRGB color production was used to create this image.

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

The raw FWHM averaged 1.4 arcseconds.

Luminance = 45 minutes binned 1x1

Red = 10 minutes binned 1x1

Green = 10 minutes binned 1x1

Blue = 20 minutes binned 1x1
