Description

The M109 group with the main galaxies M109 and NGC3953. Many faint galaxies can be found in the background. The image was taken with my Vixen R200SS at f/4.

Please compare this image to the one I took withe same scope but that time with a focal extender to f/7.5. It was the original Vixen extender. However, I have to say that the extender it not worth trying any further. There are more details in the f/4 image despite the smaller focal length. What's more, the extender delivers only a shar image in the center of the field (about APS-C) and does not work with a full format camera. The exposure time needs to be doubled.

I hope you like it. Critics is always welcome ...

Stay well!
