PST Stage 2 Mod - Upgrade
I've been using the Borg helical focuser on many PST Mods over the past few years. Very effective, but manual operation.
I've just upgraded my Stage 2 PST Mod, which has a front adaptor which allows the assembly to be mounted on the TS102/1100 or behind the SM60/ED80 as a double stack. I also fitted a Lunt Crayford focuser and added a SW motor.
A significant improvement - I can now precisely focus remotely.
To improve the aesthetics, I also added a covering "tube" on the PST etalon, with a lever adjustment......
Certainly now looks the part!
