Description

The Iris Nebula (also known as NGC 7023 and Caldwell 4) 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 designated SAO 19158. 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.

This is the first light with the both askar400 in parallel system. one with 2600mm, and the other with the 2600mc at the same imaging time.

I made 158 x 180s with ZWO 2600MM pro in Luminance, and 102 x 180s with the ZWO 2600MC pro.
