Description

3 clear nights in the space of a week!
One of the targets I chose was a group of bright nebulae around LBN581 with some Ha emission for good measure. I got plenty of data so could be picky about what I kept - must have been some thin cloud on one night so alot of that data got thrown out via subframeselector.
This is the first time I tried GraXpert for gradient removal and it seemed to do a pretty good job, the background characteristics being very similar on each channel.
Final luminance was a L/Ha blend, with Ha blended into the red channel via Pixelmath.
