Abell 85, sometimes known as the Medulla nebula, is a faint supernova remnant almost 10,000 light years away. It appears around the same size as the moon, just north of the right-most star of the famous W of Cassiopeia. In reality, it is over 300 billion times further away than the moon and hence also 300 billion times bigger.

This image is the first collaboration between James (@clarkjames70 on Twitter), Clem (@astrofisching) and Ollie (@carefreeastro) with data collection spread over several nights from early November to mid December 2022, from our three home locations, using 7 scopes, 6 cameras, 5 mounts and lots of patience with the UK weather.

In total we collected just under 200 hours of data with over 50 hours rejected, using 142.5 hours worth for this final image. In processing, we loved the look of the luminance image, so I've included this too.

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.
