Cursed By Medusa (Sh2-274)

Medusa Nebula (Abell 21/Sh2-274). This Medusa--a planetary nebula in Gemini--did not turn me to stone, but she still managed to curse this project.

Over two nights, my C6's corrector plate cracked; my Hyperstar required a re-alignment; my new ASI Air Plus lost its wifi chronically when I was inches away; and my humble Evolution Alt-Az mount's battery died early, mercifully cutting this sad scene short.

This one simply wasn't meant to be. So, for the moment at least, I decided to settle for this processed (but uncalibrated) live stack, which aggregates 725 20-second frames for a total of 4 hours integration.

I'd like to add more data, but I have to steel myself before I face Medusa again.

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.
