IFN near Polaris

This is really messy data. In my efforts to image Integrated Flux Nebulosity (IFN) I have here aimed the scope towards the North Celestial Pole. Guiding does not work there (at least not for me) and PHD2 refused to calibrate. So I ended up with 120 s unguided subs and it kind of worked for about two hours before the image started to rotate. All subs had poor elongated stars. Still, I had a go at processing it since there seem to be very few images of this area.

I had to shape the stars with sliding layers and blend mode darken in PS. I used EZ Star Reduction in PI. Finally I have down sampled the image drastically to hide the worst noise from pixel peepers ;-).

The image shows parts of Mandel-Wilson 1, the "Polaris Nebula". The shine from Polaris can be seen in the top right corner. The image also contains the North Celetial Pole.

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.
