Hartl-Dengel-Weinberger 3 (HDW 3)

This is my last image for 2023. I spent two years collecting data because this time of year yields very few clear nights here in Michigan. I would have loved to capture even more, but that is obviously not in the cards.

Hartl-Dengel-Weinberger 3 (HDW 3, PK149-09.1, PN G149.4-09.2) is Planetary Nebula in Perseus that is a large highly evolved and extremely faint planetary nebula with very low surface brightness. The central star (which is the faint blue star near the center of the nebula arc) is designated WD 0322+452. Its distinctive braided shape is the result of the planetary nebula colliding with the interstellar gas around it as the nebula moves through the galaxy. This causes the shock front to be brighter as it's getting more ultraviolet radiation, whereas the opposite side of HDW 3 is getting less UV radiation and has become invisible.

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.
