NGC 6104
Barred spiral galaxy in the constellation Corona Borealis
From Wikipedia, the free encyclopedia
NGC 6104 is a barred spiral galaxy located in the constellation Corona Borealis. It is designated as S(R)Pec in the galaxy morphological classification scheme, though it is clearly a barred spiral (deserving of the SB(R)Pec designation), and was discovered by William Herschel on 16 May 1787. The galaxy is approximately 388 million light-years away.[1][2][3]
