Thanks guys. It's a 250mm F7.3 mirror the same one I made about 8 months ago. The picture might be a little misleading because it's actually a little bigger than it looks. Here is another picture (Sorry but if i turn it the right way up it comes up skinnier). The bloke in the picture is my dad and he is about 1.75m and over 110Kgs. Problems I had many. Ther were lot's of things I had to work out and improvise as well. Attaching the tubes to the secondary cage was tricky as was getting the torque equations right. I still have a little tweaking to do but I'm waiting for a clear night to do it. I'll send more pictures and a little more details during the week.
regards Cristian
