Description

IC 4604 is the large reflection nebula surrounding the triple star Rho Ophiuchi in the constellation Ophiuchus. Rho Ophiuchi (center of field) is embedded in a large complex of nebular gas and dust that, actually, makes the star appear 1.45 magnitudes dimmer than it actually is.

The Rho Ophiuchi cloud complex lies at a distance of 427 light-years from Earth and covers an area of 4.5 by 6.5 degrees in the sky, so this is just a tiny portion of the entire cloud complex. I really like the various shades of blue in the reflection nebula and the dark nebulae embedded within.

This data was taken at DSW-Chile with the TOA-150 and consists of 6.67 hours of LRGB subs @300s.

Anyway, hope ya like it!

Tom
