NGC 3628

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

On this page I collect my observations of the spiral galaxy NGC 3628 in the constellation Leo, which is seen from the edge. Together with M 65 and M 66 it forms the Leo Triplet (Arp 317, Holm 246).

Introduction

The spiral galaxy NGC 3628 in the constellation Leo is forms a conspicuous group with M 65 and M 66 (Leo Triplet, Arp 317, Holm 246) and is seen from the edge; it is the faintest of the three galaxies in the triplet. The Leo Triplet cannot be observed as a whole in the eVscope (2) (about 1.2° distance to the other two galaxies), but this is possible with the Vespera.
