NEW DISCOVERY: Strottner-Drechsler 98 - The Opal Nebula

StDr98 is a potential planetary nebula in the constellation of Cassiopeia at a distance of approximately 965 light years from Earth. StDr98 was discovered by Xavier Strottner and Marcel Drechsler in early 2020.

Everything is double at StDr98, thats no exaggeration, because in this photo another PN candidate is hidden in the photo! On the right above StDr98 there is - surprise - StDr97, another discovery by Xavier and Marcel.

One of the most interesting aspects of StDr98 is probably not its magnificent appearance with the two huge arcs and the blue centre that reminds of a gemstone. Almost even more exciting is its centre, which is not (as usual) formed by a white dwarf star, but by two white dwarfs. A binary system of two white dwarfs in the centre of a planetary nebula is extremely rare.

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.
