Description

Ha - 22x500s bin 1x1

O3 - 28x500s bin 1x1

SII - 10-500s bin 1x1

Darks x 22

Flats x 60

This is my first finished narrowband image. Processing is incredibly tricky... maybe this target in particular. Getting the O3 layers to come out was like pulling teeth out.

Also had some issues with disc halos over bright stars. Lots to learn, thanks for looking!
