Quasar in Draco
Quasars are the very active nuclei of relatively young galaxies, emitting incredible amounts of enery that allows them to be seen at great distances. Markarian 205 is estimated to be about 1 billion light years away, making it one of the most distant objects I have ever seen through my 18-inch telescope.
Quasars are not impressive to look at. They look just like stars (as can be seen in this image), and it only through a spectral analysis of their redshifts that their vast distances are revealed.
Also visible in the photo are at least four galaxies, including the barred spiral galaxy NGC 4319, which is just above Markarian 205 and helps greatly in locating this dim object.
Image details: 13 images, each 150 seconds at ISO 1600, taken with a Canon 400D camera through a Meade 12” telescope at f/10.
