Description

NGC 6791 is a distant open cluster visible in the constellation Lyra, with magnitude 9.5 and diameter 16'.
It appears rather rich and very concentrated and is one of the oldest open clusters known, having an estimated age of around 8 billion years.
It is located 13,300 light years away, almost outside the galactic disk.
The photo was taken from my home location, under a sky very polluted by lights and above all not very clear due to a constant layer of humidity.
The image is a consistent crop of the original frame.
