PST Stage 2 Mod - Upgrade

Post by Merlin66 » Sat Mar 31, 2018 12:30 am

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!

Thanks guys!
I'll post some images of the final assembly on the TS102/1100 - and hopefully some solar images using the ASI 183MM.
