IC 4603 is reflection nebula in Ophiuchus. This is a very colorful area of the Milky Way, this reflection nebula is surrounded by dark nebula,  which is gas too dense to let light pass through. Taken with a cooled ccd camera, a QSI583wsg and a Borg 125mm f3.8 refractor. This combination yields an effective focal length of 484mm. This is a total of about 3 hours of exposure time, the monochrome images are taken through color filters and then calibrated and stacked to produce the color image. Taken on the night of June 4, 2011, near the town of Anza, CA.
