Galaxies - Coma Berenices

Introduction | Galaxies (Messier) | Galaxies (NGC) | Large-FOV Photos | Links

On this page I show photos of galaxies from the "larger region" Coma Berenices, which I took with different cameras. Partially, I have had the photos evaluated and labeled nova.astrometry.net, so that one can find the larger galaxies more easily.

Introduction

From April to June is "galaxy time", and so I photograph and observe more galaxies during this time. With the eVscope, this means that because of the small field of view (about the size of the moon), I generally get only one galaxy on a photo; only in exceptional cases it can be more. Since acquiring the ZWO ASI294, however, I can take larger fields of view; on the PS 72/432 refractor, for example, I get a field of view of a good 2.5° x 1.7° - the largest I can achieve with my equipment. As a result, depending on the area of sky in which it was taken, a photograph may contain a large number of galaxies, most of which are very small. However, because of the large field of view, even the larger galaxies in the photos are quite small.

On this page I show galaxies, partly alone, partly together with a few others, and partly on overview photos, on which one can recognize the galaxies only with difficulty. I therefore let evaluate and label the overview photos by nova.astrometry.net, so that one finds the larger galaxies more easily.

This page is dedicated to the "larger region " Coma Berenices (only larger galaxies are shown in the following map):

Map: Larger galaxies in the constellation Coma Berenices

Larger galaxies: M 64, M 85, M 88, M 91, M 98, M 99, M 100; most of these galaxies belong to the Virgo Galaxy Cluster, which starts at about M 85.

 

Galaxies (Messier)

Galaxies (NGC)

NGC Galaxies: NGC 4298/4302, NGC 4394, NGC 4559, NGC 4565, NGC 4725/16

Large-FOV Photos

The following rich-field photos were taken with the ZWO ASI294 camera at the PS 72/432 refractor (field of view 2.5° x 1.7°; controlled by StellarMate; AZ-GTi mount). Details of the galaxies are hardly visible on the photos, but many other smaller galaxies are.

Note: It is quite instructive to display the large versions of a photo (photo and analysis with nova.astrometry.net) side by side in tabs in the Web browser. Then you can switch between the tabs and thus "turn on and off" the captions.
