RHO Ophiuchi

After 5 hours journey from home i finally reached Bortle 2 sky . The RHO Ophiuchi is on my checklist from the moment I started astrophotography and finally I did it.
Its one of the most colorful region in the sky as different nebulas and colorful interstellar dust are included.
In the center of the image you could see "Antares" the red supergiant star and the heart of the Scorpius constellation. It lies 550 light years away from Earth The blue star on the top surrounded by the red nebula on is "Al Niyat" Star as Arab called it.
On the left you could see the Blue nebula IC4604 and the blue stars RHO Ophiuchi A&B which gives its name to the region.
The Dark river or the lanes of dark dust along the bottom half of the image are dark nebula which obscure the background stars. They extend for 100 light years into Sagittarius.

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.
