North American Nebula – SHO (Simulated)

A miracle happened, I finally got some clear skies on a weekend night when the moon was not up or bright. It just so happened that Milky Way “season” has just begun so I was finally able to put my new scope – the Radian Raptor 61 – through its paces and image something I have been waiting to image since last November – The North American Nebula (NGC 7000).

Imaging Notes:
I felt like the focus was a little soft. I realized this about 3/4 of the way through the session and decided to roll with it and keep my fingers crossed it would end up alright.
I was able to get 3 hours and 35 minutes of total integration – essentially from the moment it rose above the trees to the East until the ambient light from the pending sun rise began to wash out the nebula.

Processing Notes:
Stacked and channels separated in Astro Pixel Processor –
– Extracted Ha & Oiii, simulated Sii with Ha-Oiii Mono
