North is down in this image.  NGC2683 is a spiral galaxy viewed nearly edge on. However, it is sufficiently angled to see its bright core, reddish dust lanes silhouetted by star light, and blue star clusters. This galaxy has also been nicknamed the "UFO Galaxy".  NGC 2683 has been considered an unbarred spiral but recent evidence suggests it may be a barred spiral similar to our own Milky Way. In this wider field view of  NGC 2683, there are many smaller galaxies that are better seen in the larger view. NGC 2683 is estimated to be between 16 to 25 million light years distant from Earth and receding at 250 miles/sec.   The Horizontal FOV is 38'.

Image center is located approximately - Equatorial 2000: RA: 08h 52m 42s Dec: +33°25'00"
