On this page I collect my observations of the elliptical galaxy M 105 (NGC 3379) in
the constellation Leo as well as of the
two galaxies NGC 3384 (elliptical) and NGC 3389 (spiral).
Introduction
The elliptic galaxy M 105 in
the constellation Leo is bright and can be seen together
with the galaxies NGC 3384 (elliptical, physical companion of M 105) and the smaller NGC 3389 (spiral, far in the background)
in the same field of view in the eVscope. All three galaxies form a
trio of galaxies in the Leo I galaxy group (or M 96 group), which also includes M 95 and M 96.
