Revision title: M13 Hercules Cluster

I started off trying to accumulate 15 hours of data for this, and then read that Globs just don't require much. That enabled me to ruthlessly cull what I had. The individual subs were probably still too long (120 seconds each), but live and learn.

Title: M13 PixInsight Reprocessed

Description: Recently I started using NormalizedScaleGradient with very good results. Unfortunately, NSG did not think much of my Blue data and rejected half of it - and I did not have very much to start with.

Even so, still an improvement over my effort almost one year ago. I wanted to bring out that tiny detail on NGC 6207 (as well as M13) and pushed kinda hard with HDRMT and LHE ;-)

Title: M13 Hercules Cluster Revised

Description: One last go at this old data.

Recently I revised M5 and thought this would go almost exactly the same. Wrong! The Cookbook Approach to processing just doesn't work. Each data set seems to be its own unique animal, even on similar targets.

In this case, I could not get a good result at all using pseudo-luminance using the exact HDRMT and LHE settings. Tried different settings. Tried MLT. Evenually gave up on the pseudo-lum altogether.

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.
