he Iris Nebula is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487.
The nebula, which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star in the center. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alfirk). It lies 1,300 light-years away and is six light-years across.
I took this with my 8″ Celestron SCT on an AVX mount using a ZWO ASI2600MC Pro camera. There are 83 1 minute subs. I used PixInstight to process. I think I am going to do this one again but more integration time.
