Description

IC 4604 is a large diffuse nebula of 5th magnitude located in the southwestern corner of the constellation Ophiuchus, surrounding the bright triple star Rho Ophiuchi. Several regions of bright and dark nebulosity surround this area, which takes its name from ρ Oph. At a distance of some 540 light-years, IC 4604 is one of the nearest star-forming regions to the Sun. The colorful clouds surrounding Rho Ophiuchi represent the visible counterpart of a much larger but invisible molecular cloud permeating the region. This Ophiuchus cloud lies well above the plane of the galaxy, near the border of the Scorpius-Centaurus OB association. About 1.5 million years ago, a massive star in upper Scorpius exploded as a supernova, sending a powerful shock wave through the Ophiuchus cloud about 1 million years ago, triggering star formation that is still continuing today.  iOptron CEM70, ASKAR FRA300, ASI2600MC, Antlia ALP-T filter. Bortle  1  Processed in Pixinsight. Mount: iOptron CEM70Imaging Scope: ASKAR FRA300Imaging Camera: ZWO ASI2600MC ProFilters: Antlia TriBandGuiding: ZWO OAG-L, ZWO ASI174MM miniControl: ZWO ASIAIR Plus
