The Great Rho Ophiuchus Antaries Nebula Complex

At aout 500 light-years away the Rho Ophiuchi star clouds are well in front of the nearby globular star cluster M4. M4 is to the right of Antaries.

It is interesting the number of different nebula and object types concentrated in this patch of sky. The bluish colors are reflection nebula, the redish are emission nebula the darker are obscuring dust clouds, there are bright stars, VdB objects, a handfull of globular clusters, and dust permitting a couple of galaxies. Turely a spictacular patch of night sky. There is EM-radiation and light emitted at every wavelength from radio waves to gamma-rays...

This is a 6-panel mosaic that was integrated most clear moonless nights over the past several months. A project I have started several times over the years with varous instruments and will continue to work with this one.

The astrograph is a home made catadioptric 8" F/2.6.

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.
