Abell 2151, One Night of LRGB (Full and Cropped Versions)

Revision title: 2nd Night adding 7 hours of Luminance

Part of the Hercules Supercluster, The Hercules Cluster, or Abell 2151, is comprised of nearly 200 interacting structures approximately 500 light years away, many of them odd or peculiar Arp catalog members. According to Wiki, the Hercules Cluster, along with the Coma and Leo galaxy clusters comprise the Great Wall filament or super-structure, which itself spans over 500 million light years.

Since I am still new to mono imaging, and because on the continued cloudy nights in SW Ohio, I wanted to take advantage of a crystal clear night assuming I would not get another chance anytime soon to add more data; I wanted to see what what could be achieved with one night LRGB imaging. Clearly, the image needs additional luminance data. Integrating the LRGB masters into a "Super-Lum" helped a little bit. One of the two tidal tails off of IC 1182 are barely perceived extending inferiorly, and the other is not seen at all. Hopefully we will have a clear night in the next few weeks to add this data.

Title: 2nd Night adding 7 hours of Luminance

Description: Clearly, figuring out the LRGB part of mono helps a great deal. not sure if adding 7 hours of RGB would have had the same impact as 7 hours of Luminance.

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.
