IC2177 - Gum 1&2 - Seagull Nebula with Gum 3 - 4/1/2014 (Re-processed Cropped Stack)
Reprocessed for Worth 1000's Sky 2014 competition.... 4th out of 51 entries.
Gum 1 - The head of the Seagull nebula is both an HII region and reflection nebula. Gum 2 - The wings of the Seagull Nebula is a large HII shell surrounding some bright hot UV radiant stars. Gum 3 at tip of LH wing (RHS image)
A first semi-dark sky imaging of this object with my new Astrophotography modified Canon 70D from Perth Observatory, 30Km east of the Perth CBD. It compares very well to a prior attempt at the same location 10/1/2013 with f/4, 8" Newtonian, showing the greater Hydrogen-Alpha red sensitivity from the AP modification. This is probably my best image of this to date.
