Looking good there Bird,
What will the overall weight be with the 16" mirror in this tube assembly?
How much will you need, as far as counterweights go?
I have 50 kg of counter weights on my 16, 45 kg of adjustable weights consisting of 4 x 10kg and 1 x 5 kg individual weights that have 1" BSW internal threads that I can run up or down a length of 1" BSW studding, with a single 5kg end cap that locks onto the end of the studding.
I suspect my tube would be heavier than your tube and my primary mirror cell would be double the weight of yours.
I look forward to following the development of Nemesis.
Regards
Trevor
