Messier 95 (M 95)

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

On this page I collect my observations of the barred spiral galaxie M 95 (NGC 3351) in the constellation Leo.

Introduction

The galaxy M 95 in the constellation Leo is part of a galaxy group, the M 96 group, to which also M 105, M 96, NGC 3384, NGC 3377 and further galaxies (NGC 3299, NGC 3412, NGC 3489) belong. The M 96 group forms, together with the M 66 group (Leo Triplet, Arp 317; consists of M 65, M 66, and NGC 3628) the Leo I group.

M 95 is a s mall barred spiral galaxy, relatively faint, but the bar is visible. It forms a pair with M 96, but both are too far away for the eVscope (40') to be seen together. In the Vespera (Pro), you can observe them together without any problems, and also include M 105.

The galaxy IC 643 (on some photos) is lenticular and more than 300 million light years away. The barred spiral galaxy (on one photo) IC 648 is even 474 million light years away.

The elliptical galaxy M 105 in the constellation Leo with the two galaxies NGC 3384 and NGC 3389 form a galaxy trio, but no group; the first two belong to the galaxy group Leo I, which also includes M 95 and M 96. Moreover, you can see the much more distant galaxies IC 643 and IC 648. (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
