Re: [ATM] New minimalist single-pole 18" ultralight

Ross,

It looks really cool, and very innovative. Great job!

I am skeptical about a few points on its performance that perhaps we can 
discuss. The 3 point altitude bearings are an idea I toyed with but 
abandoned because of stability issues. If you consider the area between 
the altitude support points, this has 1/2 the area of a traditional dob, 
and the center of mass of the scope is actually towards the narrow end 
of the triangle. In my prototype this made the scope a bit tippy and 
wobbly. Also, the single pole looks like it would be a source of flexure 
and be bouncy when the scope is moved.

Can you tell us about the mechanical performance of the scope for high 
power viewing? Have you been able to solve or mitigate the problems I had?

Thanks, and clear skies.
