Jones 1

This is PK 104-29.1 or more commonly known as Jones 1, a Planetary Nebula in the constellation Pegasus, discovered in 1942 by Rebecca Jones of Harvard University.

The Oiii emission is slightly stronger than Ha and as the emissions almost perfectly overlap, the palette chosen makes it blueish-white, except at the center and just under the main nebula where the Ha dominates.

Jones 1 is a type IIIb planetary nebula, about 2300 light years away and with an angular size 5'-6' in diameter. The shell is of the 15th magnitude and the central star is of the 16th magnitude.

All exposures are unguided 120s at f/2 and binned 1x1. A dynamic combination of Ha and Oiii was used. Image is cropped and drizzled.

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.
