The image above is a two panel mosaic that includes IC4604 and IC4603. These two objects, and the reflection nebula surrounding them, are part of the large Rho Ophiuchi Cloud Complex in the constellation Ophiuchus. (North is to the left.) This nebular complex is approximately 400 light-years from the Earth. IC4604 is centered on Rho Ophiuchi, the triple star system to the left, and IC4603 is centered on the two bright stars located right of center in the image above.
