PuWe1 (Purgathofer-Weinberger 1), close-up and wide field with dust

I spotted this as a good target for later on in the night at this time of year. It's a very large PN at around 20' diameter, and one of the closest to us at around 1200 light years. It is faint though, and was only discovered from the Palomar Survey plates in 1980.

I found that I had 48 minutes of exposures from two years ago, which I had totally forgotten about. Lots was added to this with the NBZ filter, totalling 7h 15', which I think is as much as I've ever shot on one panel. I also took about 50' worth of broadband exposures for the stars. When processed, the broadband image revealed a dusty backdrop, leaving me unsure which way to process. So here are two versions, one close-up - narrowband with RGB stars, and one wide field - broadband with enhanced narrowband for the PN.

Description: Oops. I was so impressed with the tight stars of my cropped version, until I noticed that I'd put them back in at the wrong scale!

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.
