Sh2-224 • Supernova Remnant in HOO

Even with over 100 hours of integration time, I still had a major challenge processing this data at f/7. In addition, even though I used narrowband filters, these fainter objects still get affected by my heavy light pollution. I had to push it really hard to get the detail I wanted out of it. Subsequently I had a lot of processing artifacts to clean up as well. This is the first time I have done over 100 hours of integration time and the first time I did all that within the same season of the same year. We were fortunate to have a lot of clear nights recently, which is the first time for me this time of year here in Michigan since I started astrophotography in 2016.

Sh2-224 is a very faint supernova remnant located approximately 14,700 lightyears distant in the constellation Auriga. This unusual celestial object is also designated VRO 42.05.01. The nebula created by the supernova explosion is composed of two visual parts. It is postulated the supernova explosion created a bubble like structure, visible in the top of the image. As the shockwave from the explosion progressed into a very low density region of the interstellar medium, a "wing" component was expelled, visible in the bottom of the image.

Supernova explosions are the end stage of the natural life cycle of very large stars. Such events are responsible for the distribution of heavy elements into the interstellar medium where they are incorporated in the birth of new star systems. Without this phenomenon, planets, such as the Earth along with life as we know it, would not be possible.

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.
