ZWO ASI294 Color Camera - Galaxies

On this page I present photos of multiple galaxies that I took with my ZWO ASI294MC camera. For this purpose, I had the photos evaluated and labeled by nova.astrometry.net, so that it is easier to find the larger galaxies, because even these are very small due to the large field of view.

Note: Unfortunately, I only used my ZWO ASI294MC camera very little because I kept using my electronic telescopes. So I sold the camera again at the end of November 2024, even though I had not really explored its potential yet.

 

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 catch only one galaxy on a photo; only in exceptional cases there can be more. Since acquiring the ZWO ASI294, however, I can photograph larger fields of view; with the PS 72/432 refractor, for example, I get a field of view of a about 2.5° x 1.7° - the largest FOV that I can achieve with my equipment. As a result, depending on the area of sky in which it was taken, a photo 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.

The following photos were all taken on April 28, 2022 in Erkerode (ZWO ASI294MC at PS 72/432). Thereby, I tried to photograph galaxies in the Virgo galaxy cluster, at Leo, and at Ursa Major.

It should be noted that I took the stacked photos with the StellarMate astronomy computer in control, the live stacking of which is still plagued with a lot of problems, especially regarding the image quality. In addition, the image width is reduced to 1920 pixels, which further reduces the image quality.

It is certainly quite interesting to see which and how many galaxies could be captured on 9 photos* during this one evening:

*) The 10th photo is a duplicate...

Note: In the appendix I show photos from an earlier observation evening with worse conditions (and photos).

 

Galaxies (April, 28, 2022, Erkerode)

In the following, I present only processed photos and the corresponding evaluations with nova.astrometry.net or in case of only a few galaxies in the photo a section from the photo instead of the evaluation. Under "Larger galaxies" I list only Messier and NGC objects.

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

Final Words

67 larger galaxies (M and NGC) on 9 photos, that is something that I had not achieved so far! Even theVscope cannot achieve this (I think...)! And even if I should have miscounted, the order of magnitude is correct...

Note: Unfortunately, I only used my ZWO ASI294MC camera very little because I kept using my electronic telescopes. So I sold the camera again at the end of November 2024, even though I had not really explored its potential yet.
