VdB129: This is a very faint reflection nebula (mostly below and to the left of the bright blue star, 65-Theta-Aquillae), visually in the constellation Aquilla. Although the nebula
is pretty subdued, I like the very dense and colorful star field, highlighted (literally) by 65-Theta-Aquillae, a mag 3 star; my processing software says there are 21,000 stars in this field. This scene is thought to be about 300 light-years away from us.
LRGB:285:195:165:240; All channels are the integration of 15-minute exposures through Astrodon filters. All images unbinned.
