Abell 28
PK 158+37.1

Abell 28 is a 13.5 mag Planetary Nebula in the Constellation Ursa Major with very low surface brightness and a diameter of about 5.5 arcmin. The brightness seems to be unevenly distributed over the disk. The PN has a bright rim in the NW while it is getting dimmer to the SE. The blue progenitor star 17.4 mag is staggered away from of the center.

Acquisition Notes:

Captured and processed in HaRGB filters.

Abell 28 was not a friendly target to photograph and process. The subs had very little data with minimal structure within the nebula. Even though I processed this one multiple times, I am still not satisfied with the result as this image is the best I could produce from the data. Overall tough target that I recommend for more experienced AP'ers. I'm putting this one to bed and calling it "good enough for me."

Thanks, Eddie

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.
