Raven's Heart Nebula (Sh2-224)

Raven's Heart Nebula (Sh2-224). As far as I know, this intriguing supernova remnant in Auriga has no generally accepted name (aside from its catalog designation Sh2-224). I'm dubbing it the Raven's Heart because it looks like, well, a raven perched on a heart. This image integrates nearly 25 hours of 5 minute exposure, captured over the course of over a month, and yet it's still so faint! It was quite a challenge to process, as I tried to draw out the nebula without over-stretching the background. I am grateful to @Jay Sanchez and @Ahmed Wegdan, whose advice and encouragement helped me to persevere and wring the most signal from the noise.

I'm pleased enough with this image, but never have I devoted so many hours to gathering so few precious photons! I believe this is the way the universe tells astrophotographers to switch to mono.

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.
