VdB 15 is a faint reflection nebula in the constellation Camelopardalis. The core of the nebula resembles the well known Iris nebula for color and details.
The nebula extends next to a vast Ha region that can be partially seen in one corner of the frame in the typical Ha red emission color
The image is the result of 20.5 hours integration time in HaLRGB (9hrs L, 3hrs R/G/B each, 2.5hrs Ha) and required a careful post-processing to enhance the faint details.
