Data from telescope.live. Processed in PixInsight.

This was very difficult to process - the data was good (other than around 8 Ha subs that were really BAD and I threw them out). Combining the channels resulted in a very heavily Yellowed image. Took me a few goes to get it colour balanced how I wanted. I think part of the problem was my DBE on each of the individual channels probably had data points that were on nebulosity. Anyway, after DBE, PixelMath (straight SHO), autocoor script, SCNR and then invert + SCNR and finally colorcalibration tool, I got the colours how I wanted.

I ended up using HDRMultiscale too on the main part of the nebula to bring out more detail (took like 40 minutes on my poor laptop LOL! but the results were worth it imho).

Used a synthetic L channel with deconvolution too to tighten the stars, but had to be a bit careful with dark and bright ringing and play with the settings until I was happy.

PP in Photoshop CS6 (very subtle levels, curves, hue/sat), nothing fancy. Resize to JPG.

Took me around 3 hours to complete this image.

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.
