Cas A Supernova Remnant

Revision title: Crop

This did not come out as sharp as I was hoping. Aside from a single session of OIII, my seeing was utterly terrible throughout capture. I think I'd like to come back to this one some day with the RC despite the slower speed. If anyone has feedback, I'd be happy to hear it - I'm in a permanent state of feeling out of practice and could use some constructive criticism.

As for the mapping:
The supernova remnant and stars are SHO (and I can't believe natural the stars came out - I decided they looked so good that I didn't need to grab RGB data).
The background nebulosity is HOO. I made an HOO image, removed the stars and added it to the SHO image setting it to Lighter Color. This way, the hydrogen and oxygen areas in the background are truer to color. I ultimately didn't grab much hydrogen since there's almost none in the SNR.

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.
