Description:
M105 is the brightest of the three Messier galaxies in this region. It has a
very bright center and a large and pretty bright outer halo. As with most
elliptical galaxies, M105 shows no details.
In the same field with M105 are the galaxies NGC 3384 and NGC 3389.
NGC 3384 is a bright elliptical galaxy with a bright nucleus and although it is
classified as a E7 it appears round in the eyepiece. NGC 3389 is very faint
and was suspected most of the time but firmly seen only during brief moments.
