| Designation | Leo 1 |
| Constellation | Leo (Leo) |
| Description | The sprinkling of stars at top center is one of two spheroidal galaxies in the constellation of Leo that are distant satellites of our Milky way, members of the Local Group. It was only discovered in 1950. Because of its 10' x 7.5' extension and low surface brightness, Leo 1 is much fainter than its official mag 10.2 suggests. Observation is further difficulted by mag 1.3 Regulus, which is only 20 arcmin to the south and has cast shadows and halos in this 30' x 46' field of view. |
