Rho Ophiuchi Mosaic

Rho Ophiuchi Mosaic:
A project I worked on for several weeks: a 3 x 3 mosaic of the Rho Ophiuchi region. Certainly the best Rho Ophiuchi image I have ever made.

This is a stack of about 5 mosaic sessions (some nights could not finish complete plan runs or had bad subs). Each panel of each mosaic is 5 x 300" subs (final total exposure time about 16.5 hours).

The AM5 + ASIAIR made the imaging sessions very convenient and automated. APP has very powerful mosaic capabilities, but still requires a lot of working and processing time to integrate and tweak a mosaic like this one.

Scope: Redcat 51
Camera: ASI071MC-Cool
Guide: ASIAIR Plus
Mount: AM5

Post: APP, Photoshop (StarXterminator, NoiseXterminator, AstoFlatsPro, StarSpikesPro)

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.
