Description |
The spiral galaxy Messier 33 in constellation Triangulum. This image should only be a test for the modification of my Gemini 41 Mount. I had always guide errors in RA direction which could not be determined. But then I worked out that one of the four RA motor cables had a cold solder joint. After the modification the mount is working ! I wondered about the details found in M33. Especially the details in NGC 604 are impressive for such a small aperture instrument. |
Here you see a 300 % crop of the HA Regions in the northern part of M33
