NEW DISCOVERY: Patchick-Strottner-Drechsler 3 (PaStDr 3) in Andromeda
We are very happy to present a new collaboration with the great astrophotographer Markus Blauensteiner!

Coordinates: 01:19:28.88 +49:01:09.38
Constellation: Andromeda
Size: 12 arcminutes

Patchick-Strottner-Drechsler 3 (PaStDr3 / PNG 127.6-13.5) is a probable planetary nebula around a particularly hot subdwarf (subgroup of white dwarfs)
in the constellation Andromeda, discovered in 2020 by the French-German-American team of Dana Patchick, Xavier Strottner, and Marcel Drechsler.
Unusual for a planetary nebula is the absence of [OIII], however this object could be a rare H-alpha-[NII] - PN, as also revealed by the spectrum already taken
by Pascal le Dû. More information about PaStDr3: planetarynebulae.net

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.
