NGC 2683 is a spiral galaxy visible in the constellation Lynx, with an apparent size of 9.3'x2.2' and magnitude 10.6.
It is known among amateur astronomers as the UFO Galaxy, due to its shape very similar to a flying saucer seen almost side-on.
In fact, it is inclined by 78°, showing a very compact nucleus and an area rich in dust on the opposite side of the disk.
The external parts of the disk appear inclined compared to the internal parts: note a clear blue star formation area on the left edge (north is on the left).
