QSI 683wsg-8 -20° C   *   Takahashi FSQ-106EDX III refractor   *   f/5

The Cocoon Nebula is a cloud of glowing interstellar dust and gas in the Milky Way constellation Cygnus, an area dense with stars.

This version has over 14 hours of exposure time (double my previous attempt), but still fails to reveal all the colors I'd hoped to capture.

HaLRGB 14.5 hr exposure

L 13 x 8 min = 1.7 hr

R 18 x 8 min = 2.4 hr

G 30 x 8 min = 4 hr

B 24 x 8 min = 3.4 hr

Ha 15 x 12 min = 3 hr

L:R:G:B = [HaLRGB]:[HaR]:G:B

Prepare Super Luminance from all channels. Combine (Ha + R), G, B and combine with Super L.
