Skeleton tube from
New rocker box, groundboard and secondary light baffle.
Sadly, this telescope no longer exists - it was just too heavy and bulky for me.
But its memory lives on in its optics and the (cut down) rocker and groundboard.
I like to have a finder on the focusser board, but it does make the tube fairly secondary heavy.
Collimation is difficult, requiring two spanners to adjust each bolt, but because the tube is solid, the collimation rarely changes.
Although the altitude bearings are of small diameter, putting the pads at a wide angle increases the frictional force to the optimum. The pressure must be much higher than the 15 psi recommended for Teflon / Ebony Star, but seems fine for whatever the yellow material is.
