The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158.[1] It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.

I took this photo on a week night after work. The weather has been cloudy for most of the past 6 weeks and this was the only opportunity during this moonless phase. The seeing was poor, I usually don't image with seeing this poor. I could only get two hours worth of images. This photo is the best 1 hour 36 minutes from the 2 hours I captured.
