NGC 7293 = Helix Nebula - Revisited #3

This is my third 'Revisited' image of the Helix Nebula.

I recently upgraded my mount with the Rowan Belt Mod, which improved tracking significantly,
so I'm experimenting with longer subs, and a larger number of subs to improve signal to noise ratio.

The outer halo is just visible above and to the right of the nebula.

I've also learned a lot about post-processing using SiriL and Star Tools - thanks again to Ivo for his amazing help.

The star field in this version is possibly more refined than the previous version,, but I think #2 is a better representation of the nebula itself.

The subs are quite good though, so I'll reprocess these and see whether they justify loading up another revision.

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.
