NGC 281 The Pacman Nebula in Narrowband

I've had this on my hard drive for a few months and have finally got round to processing it! Shot over several nights in January in my back garden.

NGC 281, also known casually as the Pacman Nebula, is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. It lies about 9,500 light years from us and is 48 light years across.

If I've done this properly, the original wider fov version should be visible, but as the final version, I've gone for the crop, which I think holds up well.

I used a more natural colour blend for this image:

R = 76%*Ha + 24%*SII

G = 100%*OIII

B = 85%*OIII + 15%*Ha

For some reason, I was not expecting much from this image, but the result looks like it will be one of my favourites...the narrowband data was really good!

Captured using APT, stacked using APP and processed in Pixinsight.

Thanks for looking!

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.
