Messier 104 (M 104)

On this page I collect my observations of the spiral galaxy M 104 (NGC 4594), because of its shape, also called Sombrero Galaxy, in the constellation Virgo.

 

Introduction

The spiral galaxy M 104 in the constellation Virgo is, because of its shape, also called Sombrero Galaxy. In a visual telescope it can, according to Karkoschka, be recognized - which I can confirm (but no details...). In the eVscope, its shape is clearly visible, in the Vespera Pro as well.

Sketch

The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I observed (my impression was much fainter than the sketch): Sombrero Galaxy (Messier 104) by Michael Vlasov (Copyright © Michael Vlasov 2016)

Note: I only have the author's permission to link to the sketch.

 

Find/Identify

Find: The Sombrero Galaxy M 104 is located to the West (right) of the star Spica, which is the most conspicuous star in constellation Virgo.

Identify: If the Sombrero Galaxy M 104 in the constellation Virgo was found in the above way, it is also identified, because it stands relatively alone and also has a typical appearance (if this is recognizable...). (Image Courtesy of SkySafari Astronomy, www.simulationcurriculum.com)
