Description

This is my first imaged completed mainly with Pixinsight. The learning curve is getting a little less steep. Hope you enjoy.

NGC 7023 - Iris Nebula
NGC 7023 is a reflection nebula located in the west central section of the far northern constellation of Cepheus. The nebula contains at its center an extremely young star named V380 Cep (mag. +7.1) which is believed to have burst into life just 5,500 years ago. Since still incredibly young there is plenty of local dust surrounding the star and when starlight hits the dust it's reflected to become the visible nebula.

The Iris nebula is number 4 in the Caldwell catalog. It was discovered by Sir William Herschel on October 18, 1794.
