North America Nebula and the Cygnus Loop in Ha (Andrew_B)

North America Nebula and the Cygnus Loop in Ha

Following on from the previous images of this region I decided to get a wider field view using my 50mm lens to get the North America Nebula, Sadr Region, and the Cygnus Loop in a single frame. Once again the remarkable red sensitivity of the full-spectrum modified FujiFilm X-A3 came into its own and delivered a much better result than I'd have expected from a cheap OSC camera.

Conditions weren't great and the 7nm Baader Ha filter was working hard to keep out light pollution, moonlight, and the approaching dawn in relatively poor seeing. Disappointingly the image shows a lot of coma and is softer than I'd hoped considering the lens was stopped down to f2.0 and in future I'll be sure to stop it down further. Towards the end of the session the subs were almost completely washed out from the brightness of the twilight sky and the stack needed a lot of work in APP to pull out the detail of the nebulosity and correct vignetting.

Stars have been de-emphasised using Starnet++ and Affinity Photo to make the nebulosity more visible which is particularly effective at bringing out the detail in the Cygnus Loop.

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.
