Purgathofer-Weinberger 1 (PuWe1) with IFN

PuWe 1 is one of the largest and faintest planetaries in Lynx at a relatively close distance of 1200 light years. It was discovered by Alois Purgathofer and Ronald Weinberger in 1980 while analyzing plates from the Palomar Deep Sky Survey.

The OIII signal is slightly fainter than Ha. Since the OIII lacked any detail, a significant amount of Ha allowed interior details to be enhanced. There is a faint Ha lobe visible along the "bottom" of the nebula and a few detached Ha wisps visible "above" it. Although there is a general lack of background Ha, there is a significant amount of integrated flux nebula (IFN) in the area of the image. See "revisions" for starless images of Ha, OIII and Lum as well as a closeup showing the location of the central star.

Imaged over several nights: 12/05, 19-21, 2023; 1/2-4, 7, 2024.

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.
