Deneb to Pelican

Roughly 4X6 degrees centered on Deneb in Cygnus at 20h 41m +45d 16m. The image includes the Pelican Nebula at the lower right. North is to the left. Additional CMOS camera data added to CCD data from 2016.

This image was processed to highlight the hydrogen, SII nebula to the north, left, of Deneb. In doing this the stars of that area were supressed. An additional intent was to highlight what appears to be a blue reflective nebula around Deneb. This blue nebula is in addition to the Halpha and dust nebula in that area.

I think this blue Deneb nebula is a Halpha nebula that is tinted blue by atmospheric scattering from the overwhelming bright Deneb.

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.
