Sadr Region, central Cygnus.

What a big difference the CLS filter makes, almost looks like I did hargb. I was lucky enough to get 5 hours on this target from a green zone. DSLR cooler (thanks Stephen!) helped big time with the noise.

NGC7023 – The Iris Nebula

Recently took a week off work and since I’m trying not to spend too much money right now I decided to take my vacation at my club’s dark sky site. This is the first of many images I grabbed… nice thing about having six-seven nights to image is that I have no problem focusing on one object per night and therefore get excellent data.

From http://www.astrocruise.com/milky_way/N7023_05.htm

Object Data: Lying in the western part of Cepheus, this beautiful object is a fairly unusual pure reflection nebula, caused by light from the central magnitude 7 star, SAO 19158, being reflected off the abundance of dust particles LBN 487.
