 Located .3 degrees north of Regulus, the brightest star in Leo this extremely faint Local Group member is spread out so thinly, it is not often visible in amateur telescopes. At 11.2 magnitude and spread out over a span of 10 arcminutes - same size as M13, it defines the term "Low Surface Brightness". Leo I is classed as an E3 type galaxy, however diminutive it truly is. Several other faint galaxies dot this field, some 2 degrees across.
