The Iris Nebula is a bright reflection nebula in the constellation of Cepheus. The Iris Nebula lies 1,300 light years from earth and is 6 light years across. NGC 7023 refers to the open star cluster within the larger reflection nebula, LBN 487.

The blue appearance is caused by SAO 19158, the star responsible for lighting it up. An interesting characteristic of this object is the surrounding interstellar dust, which is clearly blocking out the stars behind it.

This was captured using a Astronomik L-2 UV+IR blocking filter which cuts out the ultraviolet and Infrared wavelengths while also suppressing any star haloing or sensor reflection that I previously had issues with. This allowed me to maintain tight stars with natural star colours.
