Camera: Atik 383L Exposure:
Exposure: 14 x 10 min (2x2 bin) and 2 x 10 min (1x1 bin) exposure with Hydrogen Alpha filter, 8 x 4
min (2x2 bin) RGB exposures. Processing: Data
Collection - Artemis Capture (as FITs). Calibrated, stacked (Kappa
Sigma Combine) - Deep Sky Stacker. LRGB channel registration, equalization, and
central gradient removal - Astroart. Curves, Levels, RGB combine -

This image is a Ha- RGB combine with Luminance layering. Color
saturation in LAB color; H-Alpha exposure stacks were used for the luminance
layer. Processing was in up-sampled data (to simulate 1x1
bin). Final Image size is approximately 2600 x 1950. North is to the
right in this
image. In this image the LBN 265 region and is dominated by that emission nebula
and is central in this image. In addition, LBN 247, 263, and 277 are also in
