From
Wikipedia:
NGC 891 (also known as
Caldwell 23) is an edge-on
unbarred spiral galaxy about
30 million light-years away in the
constellation Andromeda. It was discovered by
William Herschel on October 6 1784. The galaxy is a member of the
NGC 1023 group of galaxies in the
Local Supercluster. It has an H II nucleus.
[3]The object is visible in small to moderate size
telescopes as a faint elongated smear of light with a
dust lane visible in larger apertures.
In 1999, the
Hubble Space Telescope imaged NGC 891 in
infrared.
In 2005, due to its attractiveness and scientific interest, NGC 891 was selected to be the
first light image of the
Large Binocular Telescope.
[4] In 2012, it was again used as a first light image of the
Discovery Channel Telescope with the Large Monolithic Imager.
[5]Supernova SN 1986J was discovered on August 21, 1986 at apparent magnitude 14.
