[APML] need advice on camera mount

[Wei-Hao Wang <whwang@gmail.com>]

Hi,

I just got a new astrocamera:
    http://www.ifa.hawaii.edu/~wang/misc/200mm_69holder2.jpg
The lens is 200mm/2.8 for Mamiya 645 and the film holder is a 6x9 film 
holder modified by Mitsuboshi.  The focal plane illumination looks like this:
    http://www.ifa.hawaii.edu/~wang/misc/200mm_focal_plane.jpg
The diameter of the image circle is 80mm, not quite enough to make
a 6x7 frame but certainly much bigger than the original 645 frame.

Now I am looking for a mount for this system.   I hope to put the 
Losmandy plate on some mount and then piggyback it on my telescope.  
In this way, this camera and the telescope can point at very different 
directions (perhaps >15 degrees).  The whole system (camera + lens + 
rings + plate) is 3.7 kg.  The Manfrotto mount shown in the picture and 
normal ball heads are not strong enough, I guess.  Do you have any 
suggestions?  Any inputs are appreciated.

Clear Skies,

Wei-Hao
