Polaris with IFN

Region around Polaris showing integrated flux nebula (IFN). In contrast to the typical and well-known gaseous nebulae within the plane of the Milky Way, IFNs lie beyond the main body of the galaxy. The term was coined by Steve Mandel who defined them as "high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy) but by the energy from the integrated flux of all the stars in the Milky Way. As a result, these nebulae are incredibly faint while the nebulae clouds, an important component of the interstellar medium, are composed of dust particles, hydrogen and carbon monoxide and other elements." They are particularly prominent in the direction of both the north and south celestial poles.

Polaris could have been "tamed" a bit more through further processing, but I chose to let Polaris be a prominent part of the image. Revision is a starless image showing the abundance of galaxies in the area around the north pole.

Imaged over several nights: Nov 1-2, 5, 7, 10; Dec 4, 11-12 and 14, 2023.

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.
