Comment : This was something exiting and fantastic, a new exploding star that is so bright that you can see it through a small telescope or a binocular. I had my equipment ready. Then the night 21 to 22 in Mars I got an almost clear sky. I took the photo from the balcony and it doesn't matter very much that the light environment is very light polluted when an object is bright like this nova. This night it was reported to have a magnitude of 7.

Comment : Zoom into the nearby surrounding of the nova, 1:1 pixel relation. You find the nova just below the open cluster M52. It's in the constellation of Cassiopeia. If you live in Sweden as I do you find it in the North at midnight.
