Abell 5 Planetary Nebula

I was looking for a deep space object that wasn't going to be to hard, as the limited clear nights here in Michigan settle in over the winter. PLUS I have to send in my main ES 165mm telescope lens housing in to get the objective lens cleaned out. Over the past few years it has been building up debris in between the triplet lens.

Abell 5 is not captured often. I would suspect because it is not all that interesting of a planetary nebula. Plus it is super faint. The magnitude is quoted as 18.0. I got a few more nights than expected for this time of hear, so I piled on more Ha. I did find that I was able to pull out a bit more Ha on the outskirts of the shell, though.

The planetary nebula Abell 5 (PK 141-7.1) was discovered in 1955 by the American astronomer George Ogden Abell on the photo plates of the Palomar Observatory Sky Survey (POSS). Most of these 86 PNs discovered on the POSS photo plates are large and have a low surface brightness, which suggests that their stage of development is advanced. Abell described the PN as an incomplete ring with a diameter of 134" x 121".

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.
