CTB-1 / Abell 85 / LBN 576

My first 10-minute sub project!

Abell 85 / CBT-1. A very, very faint supernova remnant in Cassiopeia. It’s around 10,000 years old, and almost 10,000 light years away. The oiii is almost non-existent in a 10 min exposure.

A labour of love with over 70 hours of HOO data (Ha25/Oiii45) 22 nights, 425 x 600s subs. Very impressed with the detail my trusty @sky_watcher_official evostar 80mm refractor has picked up. Absolute brilliant value for money. I only lost 1 x Ha frame and 4 x Oiii frames when I was pre-processing this, so I’m super happy!

what I find very interesting, is the faint shell-like parts of the image. Quite far away from the remnant itself, they are almost the same ‘pattern’ as the outer remnant. I think this could be the shockwaves from the beginning or near the beginning, of when the star went supernova 10,000 years ago!

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.
