After reading and thinking a lot, I came to the decision, that my next telescope for astrophotography should be a VIXEN VC200L VISAC. I wanted something with a nice portion of focal length for the smaller objects and i wanted something with a flat field, a real astrograph. After some research I had 2 telescopes in my mind: The VIXEN VC200L and the Celestron Edge HD 8. The bigger versions are too heavy for my Skywatcher HEQ5 pro. I am not a friend of spikes, but at the end I liked the photos of the VISAC a little bit more than the ones of the Edge HD. So I decided to buy the VIXEN.
I talked to one of the german dealers and he told me, that the VISAC is a timeless box – especially the first generation, he gave me the advice that I should try to find a used one. And so I did and found one:
A quick look into the telescope onto the mirrow looks like this:
I am planning to use the telescope in the following 3 configurations:
- VISAC at 1800mm with EOS M100a
- VISAC at 1280mm with .71 reducer and EOS M100a
- VISAC at 4500mm inkl. 2.5x barlow lens and QHY562C
The image train of the 2nd configuration with reducer looks like this:
Here an optical test with the 2nd configuration:
The stars in the edges are little bananas, i will have to change some things to be really happy with the results.
A simple optical test with the 1st configuration:
I think it looks quite good, the stars in the lower left corner could still be a bit better, Possibly the tube needs some configuration. Further tests will show what is still to do.
All in all I have to say, that I am really happy with my new VC200L and I am looking forward to have a lot of fun with it.
