About Abell 79
The planetary nebula Abell 79 (PN A55 65, PN A66 79, PK 102-2.1) was discovered in 1955 by the American astronomer George Ogden Abell on the photo plates of the Palomar Observatory Sky Survey (POSS). A 15th magnitude PN only 1 x 0.8 arc minutes in size, it is unusually shaped consisting of an irregular and widened oval ring from which weak, oppositely directed lobes emerge, which have almost disappeared in the interstellar medium. A pronounced asymmetry can be seen in the surface brightness of the northern lobe: the northeast side is much brighter than the other. The central star is a relatively cool dwarf star that is unable to produce the ionizing radiation visible in its spectrum, which suggests an invisible, hot companion.

Which color palette to choose?
I made two color palettes with the natural RGB stars. I like the red/blue version more so than the red/yellow version. My wife prefers the latter.

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.
