Dale,
Going back to your initial question ... I would certainly go to at least 2" diameter tube. All the strength is in the surface, so diameter is what counts. If you can get some thin-wall 2.25" or 2.5" it might even be better.
Here's a 12" by Dave North. If you used a wrap-around curved secondary support/light baffle like I did it might work very nicely and would be much lighter at the top.

We're on the same wavelength Ron. I was just looking at that scope this morning. Maybe a hybrid of all three ideas. Thanks for your feedback.

Ever used an aluminum cutting blade? Oldham has a 150-tooth steel blade made for cutting aluminum. When I bought one of those, I found myself working aluminum a lot more.

Hi Ron. It was really nice to see all your scopes here in one place on the Internet. While I think I've personally seen them all, I still enjoyed looking them over again.
I want everyone to know....that not only do you build fantastic telescopes, but also you have helped countless people (me included!) with their scopes. Whether it's just helping online, or personally in some garage...you really have been there for folks. You are a true inspiration, and we are lucky to have you in this hobby.

Ron, I have just had the pleasure of running across your thread. It would seem to me that you have probably made some of the most innovative and beautiful ATM telescopes out there.
What a treat to see such lovely workmanship, something I always thoroughly enjoy looking at.
I just hope that nobody wants us to start picking out our favorite from your collection! Or maybe if there is a box marked "all" that would be alright.
A heartfelt "Thank you" for posting all those great pics. Keith

Thank you for this thread Ron. I had hoped you would do something like this for some time. Your scopes are a perfect blend of form and function.
The photo's you have posted here will help many ATMers in the future who are conteplating ideas for scopes. I for one will spend many hours looking at this thread trying to glean as much knowledge from you as possible.
You have done us all a great service.
Thanks Again

Thanks for the kind words. I hope others can get a few ideas from these scope just as I have found good ideas in others' scopes.

A small scope that gets used often is a better investment than a big scope that stays in the closet.
Unitrons, you spend more time looking at them than you do through them.
