SNR G65.3+5.7 - wide field overview (OIII)

Link: http://www.astrosurf.com/zoll/images/G65_3__5_7.html

G 65.3+5.7 ("the little Cygnus Veils"), is a faint SNR localized in Cygnus.

Many diffuse and filamentary structures compose this remnant ; SH2-91, SH2-94 and SH2-96 are some of the brightest parts. The whole structure covers a field of more than 4°, which is very similar to the size of the popular Cygnus Veils. However G65.3+5.7 is much fainter, to a larger distance of about 2500 LYs as compared with 1500 LYs for the Veils, and much older (~ 30000 years vs 7500 years).

G65.3+5.7 shows a significant signal both in Halpha and OIII ; stronger in Halpha especially in the area of SH2-91 & SH2-94, but the OIII signal allows to better estimate the whole structure and limits of the SNR, while the Halpha signal tends to merge with the surrounding galactic nebulosities.

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.
