Rho Ophiuchi cloud complex is a close and active star forming region located in the constellation of Ophiuchus. It is mainly composed of gas and dust and hosts several amazing colorful nebulae.

This region is located some 460 light-years away from Earth.

It's been a very difficult target due to its low altitude on the south horizon from my home observatory (at a latitude of 40º north).

The image has been captured using R, G, B and Luminance filters, to compose a two pane mosaic that aimed to capture an interesting part of this complex.

L: (124+160)x120" with a total of 9h28'
RGB: (15 to 25)x120" each channel with a total of 4h

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.
