Rho Ophiuchi nebular complex

The Rho Ophiuchi Cloud is a giant molecular cloud composed partly of bright ionized hydrogen and largely of dark dust; it owes its name to the star that dominates the region in which it is located, ρ Ophiuchi, located three degrees north of Antares, in the constellation Ophiuchus. With an average distance of just 420 light-years, it is one of the closest star-forming regions to the solar system; it belongs to the same galactic environment as the Scorpius-Centaurus association, from whose perturbations originated the initial compression which started the star formation processes inside it. Morphologically it appears divided into two main clouds, indicated with the abbreviations LDN 1688, which constitutes the major nucleus, and LDN 1689, with a lower mass; several dark nebulous filaments are connected to both clouds. Constellation: Ophiuchus Right Ascension: 16h 28m 06s Declination : −24° 32′ 30″[1] Distance :390-460 a.l. This magnificent field was taken by the amateur astronomer Patrizia Mazzucato with her askar 180mm ... Really a great piece to take into consideration in your setup. Congratulations on your shot because this part of the sky is difficult to shoot from its relatively low height in the sky to escape any kind of pollution. It gave me the possibility of elaborating it and adopting my elaboration method on this field surrounded by dark dust and ionized gas.

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.
