Leo II

This is an attempt to photograph a very faint spheroidal dwarf galaxy named Leo II. Because of low exposure time, and possibly not a strong enough telescope the camera couldn't grasp the galaxy in the photo. Leo II is approximately 760,000 lightyears away from our Milky Way, and even though it is a closer galaxy it is also a very small and faint one at that making it hard for observations. Scientists whom had studied and photographed the galaxy before found that Leo II had giant red stars in the inner part and outer part of the Galaxy with tens of thousands of stars within it as well. The bright stars within the photo are foreground stars that are near us, and not part of the Leo II galaxy.
