Dear Mr. Matsumoto,
For you info this was finished recently. I personally checked it out and it is fabulous.
It is saddled on a behemoth fluid head: Vinten Vision 30.
The objectives are also made by United Optics, tubes and clamps same as the recent 140ed binoscopes. 3.0 inch focuser by FT.
Comment by Matsumoto:
Congratulatinos on finishing another fine binoscope, and thank you for your timely posting!
Very simple frame-work, but sticking to the basics that promises the rigid and reliable structure.
