Messier 106 (M 106)

Introduction | Map | Find/Identify | My Best Own Photos | My Own Observations | References || Appendix: My Own Photos

On this page I collect my observations of the spiral galaxy M 106 (NGC 4258) and the small spiral galaxy NGC 4248, the galaxies NGC 4217 and NGC 4220, as well as NGC 4231 und NGC 4232 (Holm 356) in the constellation Canes Venatici.

 

Introduction

According to Stoyan, the spiral galaxy M 106 in the constellation Canes Venatici can be seen in the smallest binoculars and is an easy object for small telescopes. This is probably only true for dark skies, because I had trouble to recognize this object in the telescope at all. For the eVscope, however, this galaxy was not a problem. In addition, on some of my photos I found the small barred spiral galaxy NGC 4248 close to a star.

On a Vespera photo, I also found the galaxy NGC 4220 (lenticular; there is also the edge-on spiral galaxy NGC 4217 nearby, but not yet on a photo) as well as NGC 4231 (lenticular) and NGC 4232 (spiral). See the evaluation below! NGC 4231 and NGC 4232 form the gravitationally-coupled galaxy pair Holm 356.

Map

The spiral galaxy M 106 is located in constellation Canes Venatici, but is easiest to find from the Big Dipper (see further down). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)

Find/Identify

Find: The spiral galaxy M 106 in constellation Canes Venatici is easiest to find from the Big Dipper. I imagine a line between the two stars Dubhe and Phecda in constellation Ursa Major (or asterism Big Dipper), and if you continue this line for about the same distance, you will arrive at M 106.

Identify: If the spiral galaxy M 106 in the constellation Canes Venatici was found in the way as described above, it is also identified, because it stands relatively alone.
