Abell 29 (Gary Imm)

Celestial hemisphere: Southern · Constellation: Pyxis (Pyx) · Contains: PK244+12.1

Abell 29

This planetary nebula is located 3600 light years away in the constellation of Pyxis at a declination of -21 degrees. It is magnitude 14 and spans 6 arc-minutes in our apparent view.

The outer rim is stronger in HII while the inner section is stronger in OIII. The 18.2 magnitude blue progenitor star is identified with an arrow in the mouseover view. Thank you to Dana Patchick for finding information on this object.

Like many PN, I have a hard time understanding exactly what we are looking at here. My best guess is that we have a side-on view of the central torus region, and that the PN is bi-polar with the major axis running from lower left to upper right. This would explain why the HII region is brighter in the upper left and lower right areas, where we are looking at the thickest parts of the torus from our perspective. Both end lobes of the bi-polar PN have been blown out and are no longer visible.

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.
