Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.
An interesting compact cluster of stars in a Milky Way rich field. Top-left of centre makes me think of a flint arrowhead. Or an acorn shape.
I'm also intrigued by the somewhat darker patch at the bottom-right of the image.
Looks like there's lots of doubles in the area... I'll have to see what the WDS says. Nothing is noted in SkyTools.
I was expecting more of a gradient from the full Moon. It's pretty flat...
