Abell 80: A Planetary Nebula in Lacerta

Abell 80 is a rarely imaged 16th magnitude PN in Lacerta with a mag. 19.6 central star. This is a bicolor HOO image, but this PN is dominated by H-alpha emission to such an extent that the OIII data barely add anything besides star colors. Total integration time was 7.6 h, including 5.2 h in Ha and 2.4 h in OIII, with mostly 12 minute subs at 0.48"/pixel. I probably should have used longer subs to capture the faint, blue central star, which is just barely visible when the image is blown up. The near lack of OIII emission accounts for why people who like to observe PNs visually through an OIII filter have trouble seeing this one. Perhaps they should be looking through a Red filter instead.

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.
