NGC7000 North America Nebula in broadband

Five clear nights on the trot here in South Wales, and after pointing at some rather dim objects for the first four, I just had an hour to play with around the moon on night five. So I pointed at something a bit brighter - NGC7000. As ever, I have a battle with my RASA stars. In this image, 62 Cyg is a bit blousy at the top there. I guess the diffraction pattern is impacted by my cable management. Anyway, I've left it as it is rather than start trying to "correct" it.

Revision C: nearly a year later, this is a complete re-run of post processing. The original images have a weird purple hue and a lack of detail in some of the nebulosity. In these initial attempts I chose to use Pixinsight's ABE for background extraction due to an inability to see anything through all those stars. This was a mistake and made a mess of the end result. In this revision I've applied DBE carefully after temporarily removing the stars, and this has been much more successful.

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.
