M17 Omega ( Swan ) Nebula under Southern Skies

Post by Startrek »

Captured M17 for the second time with my 2600MC OSC under Bortle 8 skies and a 70% waxing moon
Unfortunately I had quite a noisy image to work with which did require some adjustments in AutoDev to achieve a good balanced image
Used a mask over main structure in Wipe so I wouldn’t lose too much fine detail
Overall quite satisfied with the result from imaging under such a hostile sky
