Astrophotography Equipment

New home for a VISAC VC200L

A VISAC VC200L found a new home. I am looking forward to have a lot of fun with it.

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:

  1. VISAC at 1800mm with EOS M100a
  2. VISAC at 1280mm with .71 reducer and EOS M100a
  3. VISAC at 4500mm inkl. 2.5x barlow lens and QHY562C

The image train of the 2nd configuration with reducer looks like this:

VC200L image train with .71 reducer
Here the image train I am going to use when using the focal length of 1280mm:  The 0.71 Reducer is screwed into the M60 Photo-Adapter and this M60 adapter is going to be screwed into the Draw Tube of the VISAC. On the camera side, the M60 adapter is followed by the Direct Wide Photo Adapter 60mm, followed by a T-Ring and then the Canon EOS Camera. Since I am using a mirrored M100, I have to use another adapter between the T-Ring and the camera.

Here an optical test with the 2nd configuration:

Pelican Nebula VISAC
An optical test: Pelican Nebula with the VISAC at 1280mm focal length. 5 minutes single exposure.

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:

Deneb with VISAC
An optical test: Deneb with 1800mm VISAC, 5 minutes single exposure.

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.
