Description

[Update 2023-09-10] Added Hydrogen Alpha after learning more about using Masks in PixInsight while also improving my process flow to include better noise reduction and sharpening . The image now shows the faint extended Ha halo plus enhanced Ha in the outer ring structure. 

Bortle 2+4 skies with below average to average transparency and average seeing conditions

Mixed locations: Manning Park dark sky site at 5,500' elevation (but with some forest fire smoke) + Parksville at sea level
