FOUND.................Wanted is a mirror suited to a 114mm F8 900mm focal legth Newtonian scope.
I can possibly adapt a 4 vane spider for a mirror that suits this scope.
The scope currently has a 3 vane spider for the secondary, so that would be best, but anything will do I think.
I hope someone out there has an old scope lying around that has a mirror they could sell.
Thx.
Geoffro.
