Throughout January I decided to really give my setup and skies a challenge and decided that challenge was the notoriously dim Sh2-240.

A supernova remnant showing overlapping Ha and O3 shells as the remaining gas from the long dead star ripple out in to space

I’ve tackled this before with a colour camera so I was aware of the Ha and how that might come out. I was not prepared for the minute levels of signal in O3 in all but the high signal peak area to the right side of the nebula in this orientation

A huge challenge that I’m glad is done, for now, but I think I can see myself adding to this image next year

A 1x2 panel mosaic consisting of a total of Ha 95x300s, O3 221x300s over 26 hours total. Stacked in APP, processed in PI and PS using StarNet and Russell Croman tools

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.
