I have a C8 and a Takahashi FS60c mounted side by side on a GPDX. The idea is to use one as
guidescope and the other as imaging scope. For this to be effective to 1-2 arcsecond tolerances,
it is essential that the guidescope mount is totally rigid against flexure relative to the main scope.
Other requirements are that the guidescope should be adjustable, and as light as possible, as my GPDX
has enough weight already. It should also not be so big that collisions with the mount will be very likely.
This page shows how I constructed my guidescope mount from cheap or free parts.
- The dovetail is made from a cheap metal fence piece (price about 1.2 Euro)
- The white aluminium bar is cut from a leftover piece of a shower cabinet!
- Pieces of scrap wood
- Some steel angles and screws
- 7mm plywood, I got it for free
- Sections from M6 threaded bar, plus suitable knobs.
