NGC 7293 Helix Nebula
The Helix Nebula, NGC 7293, is a planetary nebula located in the constellation Aquarius some 655 light years away.
This image was taken in bi-color using 19 x 3 minute hydrogen A and 19 x 3minute Oxygen III exposures on an SBIG st2000xm CCD camera cooled to 0'c. It was mounted on a Skywatcher Quattro 8 inch carbon fibre reflector telescope. The payload was carried an a Skywatcher NEQ6 mount, and guided with a Meade DSIii attached to a Skywatcher 102/500 guide scope.
The images were stacked and calibrated by my helper to produce the final image.
