Messier 105 (M 105), NGC 3384, NGC 3389

Introduction | Map | My Best Own Photos | My Own Observations | References || Appendix: My Own Photos

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.
