IC 10 is an outlying member of the
Local Group of galaxies.
IC 10 was discovered by Lewis Swift on October 8, 1887 and included in his
seventh list of nebulae ("Swift VII") found at the Warner Observatory,
Rochester, NY (Swift 1889). Swift describes it as
"faint star involved in a very large, extremely faint nebulosity, extremely
diffuse, in line with a star of equal magnitude which with a 3rd forms a right
J.L.E. Dreyer, in the
IC catalog of 1895 (Dreyer 1895), describes it as
"faint star involved in extremely faint and very large nebula."
It was photographed by Heber D. Curtis of
Lick Observatory on October 8, 1915, but it remained to N.U. Mayall to
reveal this object's extragalactic nature in 1935.
Edwin P. Hubble was the first to consider it
as a Local Group member in 1936. Nevertheless, this
assumption could not be confirmed until the 1960s, when
Morton S. Roberts (1962) and
Gerard de Vaucouleurs and H. Ables (1965) determined
its radial velocity and did distance estimates.
Our image was obtained by Sven Kohle and Till Credner of
with the 1-meter telescope of the Hoher List observatory. It was created from
3 exposures with a 2048x2048 CCD camera, with B, V, and H-alpha filter.
The B and V images were exposed for 30 minutes each, the H-alpha image for
245 minutes. The image is copyrighted
by the observers.
