Got some more data on M5 testing the impact of offset with my camera. Apparently I never posted a previous integration, but I've included that earlier data as well. Maybe I wasn't happy with it, I can't remember. But I'm pretty happy with the current result. I've wanted to get this guy on the new camera for a while and have been learning some better techniques to extract background / vignetting gradients as well as sharpening without overdoing things with blending.

Description: Playing around with denoise. A globular cluster is a very different beast from a nebula. I ended up using MLT to remove R with layers=4 after stretch and no further denoise. I wasn't liking the smoothing with TGVD and there generally was a lot of cruft in the background. There's not any faint background stuff I wanted to keep and this maintains crispness in the faint stars.

Description: Much cleaner core for the cluster in this pass through the data. I fiddled only a little bit with color, added some slight blue tones to contrast with existing white and hints of red.

Description: WBPP on each color channel separately and more careful processing to pull up stars without destroying color. Masked off blue stars at the end and gave them some special treatment to pull them up a bit more, just to have the color contrast between red-ish and blue-ish.

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.
