SNR G082.2+05.3
The image below uses the same data as above but with an additional 6 hours of SII emission line data - well mixed :-)
The below image is the final image - a combination of the above two images.

Super Nova Remnant (SNR) G82.2+5.3 (also referred to as W63), seems to be exclusively in the OIII emission line and requires a very long exposure time to make a visible image. (There is little or no sign of the SNR in a 10 minute exposure). The structure consists of thin sharply defined filaments that form a vaguely oval shell. It is believed to be located at a distance of 10,500 light years and based on observations, an age of between 14,000 to 21,000 years has been estimated.
This was a personal challenge – something I wanted make a full image of, since I first noticed part of it in one of my previous images. My first attempt, last year, was really quite poor. My goal here was not only to portray the faint bubble in its natural Teal colour (OIII) against the red (Ha) background, but more importantly, to try bring out those thin filaments as best I could – rather than making it a colourful blob. It took a lot of time to do that - both at the camera and at the computer.
