Flame Nebula

Flame Nebula and Horsehead Nebula as seen from the back yard.

 

This is a sum of 11 subs taken in the back yard as a part of testing. I didn't expect to get any results, so I'm pleased with the stack as it stands. There are some blown out stars resulting in color shifts that are difficult to control. Also, there are some flares on the filter that are also hard to control.

 

Still, this is a good exercise in using Pix Insight to control noise, so I'm learning.

I'll be returning to this location in the future to see what more I can get, especially in a darker location and with different filters.
