LBN576 on a self dare

Lots of images of this really cool supernova remnant lately. I'm guessing because it's a newer target...only 10 astrobin images before 2020. It's difficult...we love a challenge. It's very faint and it's large at 98 LYs across and it's in the heart of the Milky Way with lots of dust and stars in the way. I thought I'd give it a try from my B7 backyard but did not expect success...kind of a self dare. I didn't see much except stars with first night of stacked subs. Figured it just needed more time...piled up the nights...could be my longest integration time. I'm certain that the resulting image is only possible because of the recent improves in narrowband filters and camera sensors. Oh, and the new Pix processing tools. In this image I reduced the stars using by Bill Blanshan's star reduction methods. I think I reduced the stars more than any other of my images hence the mouseover of full RGB stars. So, I proved to myself that we can do this from our backyards. I think I’ll start processing from scratch sometime soon…try to use the Sii more than I did to bring out the shell more.

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.
