Messier 85 (M 85)

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

On this page I collect my observations of the elliptic galaxy M 85 (NGC 4382) in the constellation Coma Berenices (since June 2020 with supernova 2020nlp). The smaller barred spiral galaxy NGC 4394 is in the same field of view, as well as a few other galaxies.

 

Introduction

Tthe elliptic galaxy M 85 in the constellation Coma Berenices is one of the brightest galaxies in the Virgo galaxy cluster and has a bright core. The smaller barred spiral galaxy NGC 4394 is in the same field of view for the eVscope (8' distance).

On June 25, 2020, the supernova 2020nlp was discovered in M 85, and Unistellar posed the task to photograph it, which I did (July 18, 2020). Nearly a year later, the supernova was no longer visible.

In the Vespera Pro, I found besides M 85 the following galaxies:

With a distance of 908 million light years, IC 3293 is the farthest away galaxy that I have ever observed. More probably, this is an error in Wikipedia...
