First Light: Iris Nebula

The Iris Nebula is one of the most famous reflection nebulae. It is located about 1300 light years away in the constellation Cepheus. The bright reflection nebula showing the characteristic blue hue is actually a part of a larger dark dust cloud. It appears bright because light from a star embedded into the nebula is scattered (reflected) by the dust particles. It is this scattered and predominantly short-wavelength, i.e., blue light that reaches us.

This LRGB image uses a total of 10 hours exposure time. Definitely also a target to come back to for a little more data…
