Description

I had a fairly clear night, though seeing was average, transparency and cloud cover were perfect. Imaged until 3am when I ran out of sky as my roofline came into view. A fair amount of work has gone into processing, as I've been trying to correct for some strange gradients that keep showing up in odd spaces. Could be a neighbor's light, but it seemed all back yard porch lights were off this night, so I don't know what it's from.

Description: Reprocessed in PixInsight with better color correction. I could probably still improve on this, but it's already better than before!
