Regulus and Leo I dwarf (UGC 5470) Credit: Giuseppe Donatiello RA 10h 08m 22.311s Dec +11° 58′ 01.95″ Regulus , α Leonis (α Leo), is the brightest star in Leo and one of the brightest in the night sky, lying approximately 79 light-years from the Sun. RA: 10h 08m 27.4s Dec: +12° 18′ 27″ Leo I is a dwarf spheroidal galaxy in Leo at 820,000 light-years. It is part of the Local Group of galaxies as satellite of our Milky Way (properly, Galaxy) . It was discovered in 1950 by Albert George Wilson on photographic plates of the Palomar Observatory Sky Survey (POSS). The proximity of Regulus (Alfa Leo) and the low brightness make it very difficult to observe it. (127ED f/9 + EOS 4000D - 2h total exposure on Avalon M-zero observatory EQ mount) |
