Helix Nebula

This was never going to work perfectly and I knew this going into it. It's very noisy and has very little detail and that's because I can only image it for 75 minutes at a time from 26° to 18° - between a tree and my roof - mostly over Philadelphia. There were nights that the light pollution was so significant that I had trouble keeping a guide star. In addition, my tracking that low on the horizon was absolutely terrible and I had issues with star trailing. Since just about every sub was bad, I just left them all in and didn't cull any subs unless they had a plane in them. The data are flawed, I knew they would be, but I love this subject so much that I couldn't resist imaging it.

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.
