Congratulations. That is a lot of glass and should be a lot of telescope. Will you be resting it on 3 points? How about edge support? Will it be alt/az mounted?
Hi there David - yes, it is
a lot of telescope *lol* Long story short, I was planning selling up my small house with no garden, to somewhere with a better view of the skies, and decided to start building the telescope that I wanted to use. However, recession, redundancy and everything else happened, so now it looks like I'm staying put, studying as a "mature student", building a giant telescope!
The cell will have 3-point support and I've just cut out the edge supports, so tomorrow I'll look to attaching them. Next I have to make the push-pull bolts and then attach the cell to the backplate.
As for mounting the entire beastie - yes, it will be an alt-az. I've followed an interesting thread on here where a chappie made a 10". I'm still mulling around ideas at the moment, but then that's half the fun of making a scope :-)
