A very faint and obscure planetary nebula some 3700 light years away in the constellation Auriga.
Initially catalogued as a planetary nebula, was later thought to be misclassified and considered to be either a reflection nebula (LBN 809), an H-II region, and even a galaxy (PGC 16765). However it has recently been rediscovered as a genuine planetary nebula. It has a size of 115x126 arc seconds and is predominantly OIII. The weaker Ha signal has a similar form to the OIII signal. However there's an odd small area of red nebulosity at the top left-hand corner. This is possibly some NII emission which would be captured by the 5nm bandwith of my Ha filter (the spectrum shows that NII is present).
Discovered by Czech astronomer Dr. Luboš Kohoutek in 1962 by visually examining the National Geographic Society-Palomar Observatory Sky Survey prints at the Astronomical Institute in Prague, Czech Republic (https://ui.adsabs.harvard.edu/abs/1963BAICz..14...70K/abstract).
It has a mean surface brightness of 24.1 mag/arc sec.

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.
