NGC 3607, NGC 3608, NGC 3605, NGC 3632, NGC 3599

Introduction | Map | My Own Photos | My Own Observations | References

On this page I collect my observations of the elliptical galaxies NGC 3607, NGC 3608, and NGC 3605 (in descending size) in the constellation Leo that form the galaxy trio Holm 240. I also include two more galaxies in the neighborhood of Holm 240: the lenticular or spiral galaxy NGC 3632 (east of Holm 240) and the lenticular galaxy NGC 3599 (west of Holm 240).

 

Introduction

The three elliptical galaxies NGC 3607, NGC 3608, and NGC 3605 in the constellation Leo form the galaxy trio Holm 240 and can be observed in the same field of view in the eVscope when visiting the largest galaxy NGC 3607. If you move the field of view up, you can also see the galaxy UGC 6296 in the same field of view.
