CTB 1 / Abell 85 - SNR

Link: https://astrovirusblog.wordpress.com/2019/08/29/ctb-1-supernova-remnant/

A very faint supernova remnant in Cassiopeia, about the size of the full moon (33 arcmin) and also known as LBN 576.

CTB 1 ( sometimes written CTB1 ) or was nicknamed 'Garlic Nebula' in 2015 by late CloudyNights member Goofi and I have to admit that the nebula indeed resembles a bulb of garlic or an onion.

This area of the sky was much more interesting than I expected. The background is filled with (even fainter) H-alpha clouds and the large filament structures on the right side of the frame might be part of another supernova remnant as well. There's also this small oval structure near the bottom of the frame. I couldn't find much info about it but this appears to be a planetary nebula called PN We 2-262. I found it annotated on Jens Zippel's image of CTB 1.

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.
