Description

Trying to make the best out of the 40 minute integration time I had for this object because of clouds ruining a lot of the pictures. Trying to stretch a lot around the edges of the galaxy to get the really really weak signals, but to not make it too grainy, I had to use Gaussian blur to make it look reasonable. This is from a bottle 4 site, so the weak signal is there and didn’t get swamped fortunately. The moon showed up a little later in the evening, which didn’t help.

Because I have modified my camera, I got signal on the Ha, but it showed up as white (because I needed to balance it), so I tried to return the nebula spots (yes, I had to select them by hand) to the nice purple-ish hue you see in other pics.
