NGC 7293 - Helix Nebula in HOO

Revision title: Adding in a few more hours of data

The Helix Nebula is a spectacular planetary nebula in the constellation Aquarius, located about 650 LY away from Earth (one of the closest PNs to us!) There are lots of interesting things to see in the nebula, but I'm afraid my version is a bit lackluster due to short integration times and sub-optimal sessions. It's been a pretty atrocious winter for astrophotography for me and throwing in a big move to a new place it's been hard to find enough good clear nights to capture data. Regardless, I still think it looks pretty neat.

I did capture some Sii data on this target as well, but it's pretty weak and I struggled to find a good way to integrate the data without diluting the better details in the Ha and Oiii data. Always open to some thoughts on that.

I hope you enjoy!

Title: Adding in a few more hours of data

Description: I wasn't entirely happy with the data I collected up to the first revision, so I've been spending a few more clear nights with decent seeing collecting more subs. I think I'm happy with it for this year, and am especially pleased with how some of the central details/structure have come out. Processing isn't perfect so I may take another shot in the future, until now here's the final version in HOO.

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.
