Abell 34

This object, also known as PK 248+29.1, is a rarely imaged planetary nebula located 2400 light years away in the constellation of Hydra at a declination of -13 degrees. This 14.5 magnitude PN spans 5 arc-minutes in our apparent view, which corresponds to a diameter of 3 light years.

The OIII signal of this object is stronger than the Ha signal, which gives the object an overall bluish tint. The exception to this is in the two limbs seen at 11 o'clock and 4 o'clock, where the two signals are fairly even resulting in a whitish color. The small bright white patch at 3 o'clock looks like part of this limb but is actually a tiny galaxy (LEDA 3081651) far in the distance. The central progenitor star of the PN is clearly visible in the center as a small blue star.

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.
