There are a couple of other such scopes, some of them bigger too. In The Netherlands, ATM's make travel scopes based on the one designed by Pierre Strock: http://strock.pi.r2.3.14159.free.fr/Ast/Strock-250.html.

Here's one guy's website describing his home built telescopes: http://www.roelblog.nl/category/zelfbouw/. Some of them are directly based on the Strock, the latest one, a 350mm f/4 is a bit more radical. The website is in Dutch.

Here's another one, the smallest 8" travelscope in the world, apparently: http://www.astroforum.nl/showthread....hlight=Propdob. In Dutch too, check out the images by pressing the image links.

Then there's a commercial vendor, Sumerian Optics, http://www.sumerianoptics.com/products/alkaid/. The site is also in English, top right.

One can hypothize that we Dutch have lots of time to build travel scopes, because of the generally bad weather, and the need to travel far away to be able to see DSO's.
