Abell 30 (also known as PK 208+33.1) is a planetary nebula in Cancer constellation, with magnitude 15.6 and dimensions 2.1’x2.1’: it belongs to the restricted family of the “born again” nebulae.

Around 12500 years ago, the central star of this nebula, having depleted its hydrogen, began ejecting its outer layers creating the planetary nebula, with a spherical shell of reddish color with traces of OIII blue gas.
Then, around the year 1150 AC, the star “lit up” again, pouring into the space streams of matter rich in helium and carbon: the interaction between this “new” material with the “old “ one gave rise to the bright knots surrounding the central star and well visible in the image.
The reconstruction of this fascinating history was possible thanks to the data collected by both orbital telescopes (Hubble, Chandra, XMM-Newton) and terrestrial telescopes.

I used RGB data as base and then reinforced the channels with Ha and OIII. I pushed especially with OIII filter in order to give more visibility of the bright knots, but all in all I found this nebula very difficult both to shoot and to process.

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.
