Truss Mount Info
I am now building the Highe design scopes and offering them for sale.
The three pole design offers some very nice benefits over a truss tube design. Although they can be challenging to build, you won't have to worry about the seemingly difficult calculations for the truss tubes. For those intent on building their own scope, I am willing to give you an "email hand". I'll answer all questions. I'm sorry that I can't offer plans for these scopes. But there are several folks out there who have taken me up on the offer and are building some really nice equipement. Contact me through my website if you are interested in building one of these fine scopes.

It is true that a lot of stray light can mess up the contrast. This
is true for any scope Big dobs tend to not work well as a general rule in well lighted areas. That being said... With proper baffling, you really have no need for a light shroud. We baffle opposite the focuser, blacken all optical path surfaces (like the under side of the top ring, the inside edges of the rings, all surfaces inside the mirror box, and even have a kydex ring that goes on top of the mirror box). I've owned several scopes and the contrast is no better in any of them than in the Highe design. For years before I started producing these scopes, I used my Obsession without its shroud and I believe I had better performance. I noticed that tube currents were significantly reduced without it. The Highe design flies in the face of many long held ideas of what a scope should be. We've examined all aspects of standard truss design to see what really is necessary and have cut everything that really does not add to the observing experience. We've cut the weight down by as much as 50 percent as a result. How many 15" OTA's (mirror box, truss assembly, and cage assembly) can you lift with one hand? Michelle Stone Custom Telescopes by Plettstone http://www.plettstone.com Vermin wrote in message . .. On 8 Oct 2003 23:33:46 -0700, (Michelle Stone) That's a neat looking design Michelle. The truss set up is interesting, two in compression one in tension, neat idea. Looks really light. Speaking of light.... It does seem like allot of stray light could mess up the contrast of the image if used at a less than ideal site, and a shroud would be tricky to fit over the alt bearings. I'm not criticizing what looks to be a great design, but am interested in your thoughts on this matter. Regards, Tom L. |
