A LRGB composition with an integration time of 15 hours. The Iris Nebula, catalogued as Caldwell 4, is a bright reflection nebula located in the constellation Cepheus. The light emitted by the star cluster NGC 7023, located in the center of this nebula, reflects from the interstellar dust and gives the blue color and, due to the resemblance with the iris flower, the name of this object. The brownish area around the reflection nebula consist of “space dust” and it blocks the light from the stars behind it creating blank, dark spots in the sky.

About Andrei Bacila

I'm a Romanian astrophotographer. I live in Timisoara, Romania and shoot my astrophotographs from a moderately light polluted site in the countryside. I started doing astrophotography at the beginning of 2015 and I've been enjoying it ever since. I started with DSLR camera but later moved to a dedicated cooled CCD. My current setup consists of a SkyWatcher ED80 refractor with a 0.8x FR/FF that sits on a AZ-EQ6 GT mount. The camera I'm currently using is an Atik 460ex mono coupled with a EFW2 filter-wheel and 1.25" filters. I enjoy shooting RGB compositions but due to my location this can sometimes be difficult. Whenever my time allows it I try to travel to a less light polluted site to get better captures.
