This time I tried one of the most known object in the sky, the Ring Nebula in the constellation of Lyra. Also known as Messier 57, M57 or NGC 6720 is a planetary nebula created when a shell of ionized gas was expelled into the surrounding interstellar medium by a red giant star passing through the last stage in its evolution to become a white dwarf.
This object is located at 2,300 ly from earth and a size of 1,5 x 1 arcminutes in the sky making it almost impossible to see with a 10x50 binoculars requiring a telescope of 20 cm (8in) at least. This makes even more awesome that with my small ETX I was able to shot this image.
The shot is composed by 40 x 2 seconds exposure 10 darks and 10 bias.
I was also amazed that the image resolves the double star in ß-lyrae also know as Sheliak.
A great discovery is astrometry.net which allows you to upload the images and it automatically annotates the obects and stars pictured.
