M57 in HßHαOIII from the Nordic Optical Telescope

I believe that everybody knows that I am a big supporter of backyard astro-photography. Still enjoying those wonderful images though that are taken with professional instruments far away from any light pollution. 2 years ago I downloaded (free) data from the Nordic Optical Telescope (big thanks to @Niels V. Christensen who posted links to this site at that time). I chose M57 since I was just working on it with my own data. Once downloaded I quickly forgot about them since I had quite a backlog of my own data. Well, the backlog is gone now (2 years later, hence not too bad 😊) and I remembered that I still had those data laying around.

Some interesting numbers when comparing these data with my own sets:
Hard Disk Storage: <1/30th compared to my own
Acquisition Time: 0
Processing Time: <1/10th compared to when processing my own data.

We all see that Astrobin has lately a strong tendency to showcase the processing of professional data, and with today's tools the results are stunning, love them. On the other hand I just wonder in which direction the backyard astro-photographers here on Astrobin will go, hoping that the excitement/work/hardship/etc. of obtaining own data will always outweigh the processing of them.

Hence a huge shoutout to 2 very recently posted images of the same target:

Both images are IMHO amazing. The outer shell of M57 was just a dream to get years ago with our instruments, and both show them so clearly, great stuff!

Here a link to the Northern Optical Telescope: http://www.not.iac.es/
The Nordic Optical Telescope (NOT) is a 2.56-m telescope located at the Spanish "Roque de los Muchachos" Observatory (ORM), La Palma, Canarias, Spain.
You will find a ton of data to process if you are interested.

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.
