Iris Nebula (C4)


This image was taken from my back deck in Abbotsford in June 2013.  It consists of 5, 10 and 15 minute subs registered and combined in CCDStack and finished in Photoshop CS5.  The total exposure time was four hours.

The Iris nebula is a reflection nebula in Cepheus about 1,400 light years away. the blue colour is caused by starlight reflected from dust grains.
