Abell 39 Planetary Nebula, PK 47+42.1 in Hercules

After months of bad weather we are enjoying here in Vienna a few consecutive days of clear sky, no wind and waning crescent moon (!), and here we are.
The narrow-band signal has been recorded during 3 nights (19, 20, 21 March 2022) and I added RGB stars on the night of the 26th. OIII was stronger than expected.

This beautiful teal bubble is a planetary nebula visible in Hercules constellation. It is 3300 ly away (source Wikipedia, other sources say 7000 ly) and 4600 ly above the galactic plane. It is almost spherical, and it originated by a star that was just bigger than our sun, whose residual is the central white dwarf visible in the picture.

The bubble transparency allows to spot through it far away galaxies like PGC2817010.

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.
