Abell 33

Abell 33 is a planetary nebula in Hydra and is located some 1500 light years away. The bright star along the edge is HD 83535 - magnitude 7.2 and some 700 light years closer than Abell 33 - giving the nebula its “diamond ring” effect. The remnant of Abell 33's central progenitor star is still bright and more luminous than our own Sun. The central star appears to be double, but it is not known if this is a real association or just a chance alignment.

While there is a component of Ha, OIII is significantly brighter giving the nebula its bluish color. See revisions for relative stacked images of Ha and OIII.

Also included is a closeup of the central star region showing the "double star" - this is much sharper than normal due to an aggressive pre-stretch application of BlurXTerminator, but clearly shows both the central components.

Imaged over several nights: Feb 7-8, 15, 25-26, 2024.

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.
