Jones 1 (PK 104-29.1) - HOO with RGB Stars

PK 104-29.1, also known as "Jones 1", is a very faint, ghostlike planetary nebula in the constellation of Pegasus. This object was discovered in 1941 by the American astronomer Rebecca Jones on photo plates of the Harvard Observatory. Two years earlier, together with Richard M. Emberson, she discovered another planetary nebula: Jones-Emberson 1 (PK 164+31.1) in the constellation Lynx.

This is a large planetary nebula with an angular diameter of 320 arcseconds. The central star is magnitude 16.8 and the nebula itself is magnitude 15.6. Distance measurements range from 716 pc to 826 pc (around 2300 to 2700 light years).

I’m surprised that this object is not imaged more often as it is a striking target. The Oiii signal resolved without a lot of difficulty but the Ha did prove to be challenging. This is my first image that utilizes my new Antlia LRGB Dark series filters. Processing of the RGB channels did seem somewhat easier without some of the blue fringing I’ve experienced in the past.

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.
