Description

I finally managed to complete this project and present to you SNR G65.3+5.7 - a remnant that is not so easy to spot. The SNR is bigger than the Veil nebula as I managed to fit the Veil into a 2 panel mosaic. In order to capture the full loop of SNR G65.3+5.7 I needed to create a 4 panel (2x2) mosaic.

It took me a month to capture this image. I started in June and finished in July - I dedicated 3 nights per panel so in total the imaging took 12 nights. I had some doubts in the beginning but when I processes the first panel I was hooked and wanted to capture the whole thing.

SNR G65.3+5.7 includes three Sharpless objects in itself - SH2-91, 94 and 96. But in the catalogue of Sharpless those objects were not considered to be connected. Their real nature was discovered later in Y1977 during an OIII survey of the Milky Way when it was concluded that their nature is of SuperNova Remnant.

Speaking of the Milky Way - this object is situated on the background of a dense field of stars. I used PixInsight to count the stars in my frame and it estimated - 245 479. StarNet came to the rescue as without its help I wouldn't have managed to process this image.

It is estimated that SNR G65.3+5.7 is situated at a distance between 2 600 and 3 200 light years with an age between 20 000 and 25 000 years.
In comparison the famous Veil Nebula in Cygnus is situated at a distance of 1 470 light years and has an age of between 5 000 to 8000 years.

Hope you like my image. Constructive criticism and suggestions are welcome.

Clear skies,
Ivan
