The Popped Balloon (Abell 85 - CTB1 - LBN 576)

This goes by many names - I even saw someone call it the Garlic Nebula. I see a balloon that someone just poked with a needle. Since this is a supernova remnant it is more likely that the balloon finally reached its breaking point and we are lucky to see the initial breakthrough of the gasses.

This is an interesting processing challenge in that it is very faint and the structure of the bubble is very similar in brightness the background (or foreground?) nebulosity. I found that the SII was relatively stronger in the shell than the background, while the Ha showed less contrast. So I tried to use the SII to help separate in both color and structure.

This is 110 twenty minute subs of SHO. Total time almost 37 hours.

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.
