Re: ATM Tube construction for a permanent mounted scope
A true Serrier truss is probably the best as the design of the Serrier
provides for 0 motion of the end pieces relative to each other as the scope
moves. Another thing you may consider is providing temp compensation if you
live in an area where the temps vary a lot over the evening. This is a
complex setup so you may not want to do it tho.
