This was an interesting area to capture and process. Lots of faint nebulosity, especially in Hα, but the OIII signal was fantastically weak. SII was in between the 2 extremes. I decided to try to bring out some of the fainter structures while still preserving some of the details in the brighter nebulosity - I am not sure how well that succeeded. But while the end result was not quite what I was envisioning as the data was being collected (is it ever? 😀) I am happy with this result, which at least seems to compare reasonably favorably with other examples here on AB.

Not a lot of official info online about this pair either. Apparently located at ~7,000 light years (Spider) and ~10,000 light years (Fly) in the constellation Auriga, they both harbor some active star forming regions.

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.
