NGC 7380 Wizard (First Light) - Forums

Topic starter

Hello,

New to the hobby of Astrophotography and longtime photography but really enjoying the challenge and community. I choose NGC 7380 Wizard as my first light and decided to try to process 5 hours of data from an boral scale 6~7 area. I know I need more data to improve the quality of this but was wondering what the artifacts of blue and red that vignette my data? Could it be just city lights or moon spillage, the Optolog filter, other HA, or calibration data from bad flats? Any information or CC is greatly appreciated.

Clear Skys,
Bryan

Hi,

With Moon at 88% I'd say it is it. TVignetting is more a darkening in the corners, which is the opposite you have here.

Cheers,

I’m far from an expert Bryan, but yes the moon is giving you the gradient your seeing or at lease the majority of it anyway. I don’t know how your processing your data but in APP (and other software) you use the remove light pollution algorithm in the Tools menu to help eliminate that gradient.
Nice round stars in the image though. Once you get the gradient fixed you could probably stretch the image a bit more in curves to bring out more detail.
