Kohoutek 2-1

This object, also known as PK 173-5.1, is a planetary nebula located 3500 light years away in the constellation of Auriga at a declination of +31 degrees. This nebula spans 3 arc-minutes in our apparent view, which corresponds to a diameter of 3 light years.

This PN is one of many planetary nebulae that were named after their discoverer, Czech astronomer Dr. Luboš Kohoutek.

It is interesting that SIMBAD lists this object as a reflection nebula (LBN 809). Its entry in SIMBAD even includes a note - "This is not a PN". Well, I have imaged lots of both objects, and this is clearly a PN. There is even a dim 18th magnitude blue progenitor star at the center. Little Ha was present in this object and lots of OIII, so I didn't even bother getting Ha subs. This object reminds me of Abell 31, without the outer Ha rim.

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.
