The Little Veil Nebula

About 300 supernova remnants are known in our galaxy. The Cygnus constellation contains several of them, of which the Veil Nebula is the best known. SNR 65.3+5.7, also in Cyg, is known as the Little Veil Nebula. It is very faint, hidden by a sky rich in stars. Some of its regions were already cataloged by Sharpless as Sh2-91, 94 and 96. In 1977 Gull et al. confirmed that they were part of the same object. It's very big. It occupies about 4 x 3.3 degrees in the sky. It is at a distance of about 3000 light-years, and its diameter is about 230 light-years. Its shell mainly emits OIII signal, and also HII to a lesser degree.I started the capture with the QHY268C OSC camera and an Askar FMA 135 tube. I shot with a Baader Neodynium filter to capture the stars, then, over 6 nights, I accumulated 21h 20m of shots with the dual-band Optolong L-Extreme filter. I then received an Optolong-L-Ultimate dualband filter. The sky got worse, and I had to spend 11 more nights capturing 15h 30m with this filter. In the processing, the isolation of the stars was essential given their density, and despite the long exposure the signal was weak and difficult to highlight. I averaged the master-light of both filters at 0.5+0.5.

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.
