M105, NGC3389, NGC3384

The rightmost galaxy in this image is M105. This elliptical galaxy has the added attraction of having two other bright galaxies in the same field of view. NGC3389 is the small edge-on spiral at the left, while NGC3384 is in the center.

This is an ST-7 replacement for my original ST-6 image.

I took this picture from my driveway.
