I have a WO Z61 APO riding on an iOptron CEM 25P. I also have a Stellarvue 50mm Guidescope. The Z61 came with only a single clamshell w/no mounting saddle on top. It does have 4 screws on the scope itself for mounting 2 shoes. The Stellarvue GS came with rings and rail (post 2017). My present setup utilizes a Losmandy side by side slab rail. I'm hoping to lighten my load by mounting the GS directly to my Z61. I just need to know the proper hardware. So far I haven't had luck getting advice from OPT or Stellarvue.
Thanks in advance.
