NGC 7293 = Helix Nebula - Revisited #5

Here is another image of the Helix Nebula - the 5th time I've revisited this target.

This image was created using the same set of subs as my previous image, however it was processed using PixInsight - quite some time after capturing the original subs.

The subs were slightly under-sampled using the ASI071 camera and 400mm OTA, so I used Drizzle x 3 to enhance fine detail. I used StarExtimator to separate the nebula and stars into different layers, then used NoiseExterminator and BlurExterminator to produce a clearer rendition of the nebula and the background stars, then tools such as HDRMultiscale Transform, SCNR and SPCC to adjust the image for a more natural colour balance.

I was amazed at the improvement possible when processing the same set of subs using PixInsight compared to my previous effort.

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.
