Rho Ophiuchi and neighboring molecular clouds

Revision title: Megamosaic AAPOD2

The main goal of this project was to capture the exceptional, extremely colorful, gigantic region enclosing the emission, reflection and dark nebulae around stars named Rho Ophiuchi, Antares and Alniyat, as well as neighboring objects (M4 globular cluster and others). This region is commonly referred as Rho Ophiuchi Molecular Clouds Complex in the astronomical literature.

This 4-panel mosaic is produced by combining the integrated data collected using two different telescopes (Askar FRA400 and William Optics FLT-91) in the last two years. The same astronomic camera (ASI294 MM Pro) and same filters (Chroma RGB set) were used. The integration time is on average 4.5 hours per panel. Difference in the telescopes focal length (280 and 432 mm) and changes in the atmospheric conditions between different nights impose real processing challenge. Imaging sessions required a total of 7 car trips to two different locations by total driving around 800 km.

This updated mosaic was awarded with AAPOD2 at July 21 2022

Title: Megamosaic AAPOD2

Description: I have included the data collected last year using different scope with shorter focal length in order to increase the signal to noise ratio. This "megamosaic" was a real challenge for processing.

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.
