The Azure nebula - the Gate to Cepheus

The Azure Nebula (Strottner-Drechsler object 33 / PNG 110.2+07.9) is not only one of the most beautiful, but also one of the most mysterious discoveries of the team by Marcel Drechsler and Xavier Strottner.
This structure, formed by 2 separate arc segments, is possibly an unusual form of a planetary nebula, because in the centre of the two arcs there is a remarkable star that emits a strong ultraviolet signal, suggesting a binary system in which one of the partner stars is a white dwarf.
However, other explanations for the Azure Nebula are also possible.

This image of Strottner-Drechsler object 33 is the first ever taken and was taken by Ola Skarpen (team SkyEyE) with an incredible total exposure time of 120 hours. The image processing was done by Marcel Drechsler.

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.
