Note that the center of the dovetail holder is shifted downward by 10mm, which is the secret of the perfect balance through the stroke from horizon to zenith.
I am showing the default angle connections, but never turn the units with mirrors installed. You should put apart the units and then dodge the mirror edges before connecting at the other angle.
It is a good chance to show you the comparison of the old and new larger-housing of the EMS when the old one returned for the reform. The left one is for the FS102-BINO , now it is at my place, and the right one, in white, is the current larger-housing.
The old one, left TAKAHASHI-colored one made more than two decades ago,was molded in the sand by the traditional method, and the right white one was diecasted by the modern plant which is far more precise and thinner.
You will know by this movie how difficult it was to set the maximum sized mirror into the older housing.
