The eye of God

Helix nebula has been on my list since beginning of my astrophotography three years ago. I have never gotten the chance to shoot it. The main reason is its low on the sky from my backyard. My neighbor house also blocked half of the time when it is above horizon. Every clear night I get roughly 3.5 hours per. The project was started on 8/9/2020 and completed on 9/12/2020. It took more than a month.

The eye itself is pretty bright, but the gas surround it are faint. 5nm HA required 10 hours for my 5.5" lens. I did add 7.5 more hours to it. It didn't help much when comparing the integration at 100%. In order to get a bit touch of gold, 7 hours S2 data is also collected.

At the end of the session last week, the smoke from California wild fire hit Texas, one night data was totally deleted. It was a clear night with very bad seeing.

I took my time to process these data and tweak the color version by version. I hope this final image is appealing.

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.
