[APML] dovetail systems, help!

[Roland Roberts <roland@astrofoto.org>]

I'm trying to figure out parts for fitting together a couple of cameras
via the Losmandy dovetail system or something similar.

I have a GM8 with the "dual scope platform" (DSP) and i'm planning on
using a newly purchased Orion 120ST as a guide scope for wide field
shots.  I've also got a Canon 350XT on order from Hutech which will be
one camera, possibly mounted to a Borg 77ED (wife has approved
expenditure, wahoo!).  Another camera will be my recently acquire Pentax
67 with a 300mm lens.  And another (two if I can figure out how to mount
them) will be a Pentax KX/K100, probably at 50mm for more constellation
portrait shots.

So..., the 120ST will be mounted on one side of the DSP.  The rings have
flat spots on top for mounting another rail.  I figure I'll put
"something" for the rail and mount 108mm rings (or similar) for the
Pentax 67.  But what is the appropriate something?  I've been looking at
the Losmandy website and am confused.  I've also been looking at the ADM
mini dovetail system (http://www.astro.premcom.com/ADM/), but am still
confused.  Can someone help to unconfuse me....

TIA,

roland
