Gary,
Thanks but the scope is NOT a TSA102, rather, it is an FCT-100 fluorite triplet - Tak only made around 78 or so of these (latest guesstimate - I am still awaiting Tak to respond to my archival request), as they were so prohibitively expensive to produce.
The scope is the SAME size as the FSQ-106 and 106N (NOT the ED, EDX or EDXIII) - not surprising considering the FCT-100 gave birth to the FSQ-106 (which was cheaper and easier to make). It weighs in at 5.7kg, which is 1.3kg lighter than the FSQ-106EDXIII, and only 1.7kg heaver than the FSQ-85.
Only 1 FCT series model remains in production - if you can call on a custom basis only, and for HUGE $$$ - the FCT-250:

I have considered my options, and BOTH mounts I have SHOULD handle it. My guidescope is a converted Tak 7x50 finder with helical focuser, and weighs less than 500g all up.
Be close, but I think it can do it.
