Description

Iris Nebula is dramatic reflection nebula in the constellation Cepheus.
With plenty of dark interstellar dust is illuminated by a central hot star named SAO 19158 which is 10 times the mass of our sun.

It lies 1,300 light-years away and is six light-years across.

It was integrated only 15 hours, 50% best frames of the total valid frames taken between May and June of 2019.

PD: I am glad to check my improvements when I compare to this other capture from three years ago. :D
