Northern Wisps

Shown here are wisps of IFN near the celestial pole. This is part of a large "stream" of wisps that extends across tens of degrees of the sky- but it is outside of the frame typically captured by astrophotographers looking at structures near Polaris. If anyone knows a name for this wispy stream... let me know. It is very faint and basically colorless (at least at the S/N I am able to achieve).

One of the interesting elements of this data set is that for a large fraction of the images my camera was loose and rotating.... I demonstrate in my content on my site how to use Normalization (both Local Normalization and NSG) to make it possible to stack these frames in a seamless way. Although few people will have this particular issue- there are many issues in this family and I consider this an important real-world lesson in using PixInsight and image processing to keep data that a typical imager would throw away.

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.
