The Wizard Nebula is a large, diffuse HII region in Cepheus associated with the star cluster NGC7380. It is ionized by the binary star DH Cephei. Stewart Sharpless cataloged this as object 142 in his 1959 catalog. This image is our first result using the Astronomik 6nm H-Alpha filter. The waning gibbous Moon was at 86% illumination during acquisition.

Thanks for the kind comments, Bill. Yes, the plan is to add color. First we have to wait for clear weather to come back around so we can get the RGB data, then we will have to see how it goes since we have never combined Ha with RGB before.

C&T, excellent work. The detail is deep and real sharp. Tack sharp stars for 10 minute subs and all with a DSLR !!!! (Nice work on the S&T editor's choice BTW)

Thanks a bunch, David. This was our first time using an H-alpha filter and we were really worried about our guiding and possible flexure issues at 10 minutes. Seeing the results we got with the filter was a pleasant surprise.
