Default Soligor MT-800 with Nikon D100

I have a Nikon D100 and was thinking of buying a Soligor Mirror telescope MT-800.

Soliger themselves says this:

"This reflector telescope will impress even demanding astronomers with its extremely good focal ratio, making details of saturn and the saturn rings visible. A first choice instrument for serious astronomers."


The cost here is about $600 for it, is it a good choice or are there better alternatives?

Apparently nobody knows anything about this telescope. I can't help here myself - so the best bet is to continue asking on different forums and perhaps someone will be able to answer your questions.

Many astro-telescopes provide a port where a "T" connector can be used to connect a removable lens camera - whether that be digital or film. When this is done, the telescope becomes a fixed focal length lens at a fixed F rating. For example, the Meade ETX-90 becomes a 1250mm F13.8 lens with any removable lens camera. With a digital SLR which has a less than full 35mm frame field of view, the effective focal length will increase by the "crop" factor of the digicam. Canon D30/D60/10D have 1.6x reduced field of view so the 1250mm becomes an effective 2000mm. With the Nikon D100, D1, D1X, D1H there is a 1.5x crop factor. With the Canon 1D and most of the Kodak pro cameras based on Nikon frames, it's 1.3x and with the Canon EOS-1Ds or Kodan Pro 14n it's full frame with no crop factor.

The bottom line is that if the telescope provides a port for a 35mm camera, you don't shoot through the eyepiece with a removable lens camera. With fixed lens digicams or 35mm film cameras with fixed lenses, you "must" shoot through an eyepiece.
