Abell 20

Abell 20
PK 214 + 7.1

The Planetary Nebula Abell 20 is located in the Constellation of Canis Minor. It lies about 6500 light years away from Earth and is mainly comprised of Oxygen with a hint of Hydrogen Alpha. It is circular in shape with a Blue progenitor star in the center.

Acquisition Notes:

I didn't take RGB for the stars on this one mainly because the Moon was over half full and there was plenty of Ha to produce HOO stars. Lots of O3 in Abell 20 but Ha still showed up well in the subs. My goal was to gather equal amounts of Ha and O3 subs, but I lost it to the trees before I could finish the Ha set. Conversely, I didn't have any trouble processing this one like I did with the previous three: Abell 25, 28 and 30. Sometimes it works out and sometimes it doesn't.

Version B is the Mouseover Crop

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.
