Abell 85 / CTB-1 supernova remnant

The supernova remnant of the popped balloon nebula or also called CTB-1 or Abell 85 is the first collaboration between Kai and me. Because of its faint structures inside the nebula, it is known as one of the harder deep sky objects to capture. Challenging enough for us to give it a go and try to capture this beautiful area in the constellation of cassiopaia.
Combined we have been able to collect 66 hours and 52 minutes integration time in total. Our longest integration time so far. Due to a small rotation difference of 15° we had to give it a little crop.
But the difficulty wasn’t about getting this long integration time in spite of some fullmoon nights, but in editing of all the data. So we edited each one version and combined them afterwards. The result came out very well (that’s what we think) 😊
Let us know what you think about it.

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.
