I've been quiet in the background for the past couple of months. Moving back to Oz and doing some "mandatory" renovations etc.
Just getting/ making the time to get the gear unpacked.
First cab off the rank is the TS102 PST Mod. This 102mm f11 scope is made by Hunming (United Optics), China and sold in the UK as the LYRA. It's a great scope, and perfect for the PST mod (as others have already found)
I machined up an adaptor which just replaces the original Crayford focuser. (There's a dovetail connection on the rear of the OTA - just needs 3 x M4 nylon screws to lock it in place)The 2" PST nosepiece is held securely by 3 x M6 nylon screws. No cutting of the OTA and the adaptor can quickly be removed and replaced with the original focuser for white light observing.
I've also machined up a cell to take the SM60 etalon to give double stacking....
Good to be getting back into it.

These images show the quick change over to the Baader wedge for white light observering.
Only takes 10 sec!
