Currently, the 10" is up on our website and we will be adding the rest of the range over the next day or so.
Here's a little information:
For those who prefer a catadioptric telescope which is exceptional both for photographic and visual use, we have introduced our Optimised Dall-Kirkham series, designated ODK.
The tube is constructed from Carbon Fibre sandwich design. Very, very strong to avoid flexing and, zero expansion to ensure the focal plane does not change over long photographic exposures. Being an open tube design and very short, cool down times are remarkably fast.
To assist cool down of the telescope, each model is fitted with three fans, all positioned behind the primary mirror.
Delivery takes 10 weeks from order as each one is custom made.
