Description

UPDATE: I reprocessed and was far less aggressive on stretching the dust. I lost some of the subtle colors but the end result is that the image has a lot less noise. Which do you prefer?

I finally had a semi clear dark night last night. First in almost two months! There were intermittent clouds and the window was fairly narrow but I was able to get 2.4 hours of data! My target is 8 to 10 hours, so I can bring out the dust more, but since this is the first time out in so long I couldn't resist processing to see what I could get. As expected... it's noisy and needs more time. But its a start. Fingers crossed the next three nights have some clear sky time...

UPDATE- I got two more nights of shooting on this target and combined was able to get just over 11 hours! Feels great to see the stars again!!!
