Rho Ophiuchi Cloud Complex

Rho Ophiuchi is the namesake of the Rho Ophiuchi cloud complex. It is a primarily reflection nebula of gas and dust, which the Rho Ophiuchi system is embedded in. It is one of the easiest star forming regions to observe, as it is one of the nearest at 360 light-years (110 parsecs) away, and it is visible from both hemispheres. The interstellar extinction of Rho Ophiuchi is measured to be 1.45 magnitudes, meaning the dust and gas in front of Rho Ophiuchi absorbs light from the system, making it appear 1.45 magnitudes dimmer than it should be. The red cloud area in the upper left is associated with the Antares Nebula, which blends into the Rho Ophiuchi Cloud.

This image was captured with an ASI1600MM-C camera on a TS80 APO running at f5.5. The image consists of LRGB channels made up of 75x30 sec sub exposures for each channel, so 37.5 minutes per channel, or 150 min in total. The Lumininance layer was overlayed at reduced opacity to boost contrast.

At full screen size there it does demonstrate some graininess in parts of the cloud, and this will require more data to resolve. So I will revisit this location again.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
