This one turned out to be more interesting than I thought it would be. Obviously, M27 is a well-known and often photographed object. I myself have already shot this two times before in the past. This time I decided to shoot it in narrowband - something that is not done as often as you might think, and I also used the new ZWO ASI2600MM-Pro camera on it. I cannot say enough good things about this camera!I ended up getting 10.25 hours of integration on it. The processing turned out to be eventful as I found that shrouded in the bright nebula was some amazing detail that could be brought out - and the detail seen through each filter was VERY different. Then determining what color mapping to use was another whole story. I actually processed three complete versions of this image (SHO, HOO< and a custom mix) to completion and chose the SHO version as the final rendition - but the others are interesting as well. I hope you take a moment to check on the website post for this and the processing story on this was pretty interesting.

Below are two alternative views of the image. The first is a custom mix:

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.
