The gulf of Cygnus

The last in this imaging run, same object, different scale, mainly due to the fact that my trusty Argo Navis DTC has had to return down under for a repair, so I am back to star hopping!

52m Ha data of the great Cygnus wall or ‘gulf of Cygnus’ as I prefer. Taken in bright moonlight, at 200mm f4 using my Pentax SLR lens, it is noisier than my last image, using unguided 2m exposures. I’m really pleased to have captured some detail within the wall, surrounding emissions and dust in this fascinating region. I’m sure it would be worth adding some colour as L(Ha)RGB or even SHO palettes once dark skies return - hopefully in a week.

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.
