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. A first imaging of this object with my new Astrophotography modified Canon 70D from home in the suburbs. It compares well to a prior attempt from the darker skies of Perth Observatory 10/1/2013 with f/4, 8" Newtonian showing the greater Hydrogen-Alpha red sensitivity from the AP modification. There appears to be a gradient present that might bear reprocessing when time permits. Note: 1/3/2014 this came back to haunt me ... it looks like it was light entering via the Canon 70D viewfinder! See also cropped version this night and also same object the following night from darker skies of Perth Observatory for a much better outcome.

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. See also uncropped version.
