Setting up dual scopes on the GM2000
Parts were putchased and have been lying around since months. With Christmas break finally the time arrived to put everything together.
The setup consists of a 4″ 10micron clamp that sits on the mount’s head. Next a 10micron 4″ dovetail length 400mm. This should provide (based on sketcheds) sufficient space between the two telescopes.
At both ends of the dovetail two clamps were bolted-on: the original Baader Pan EQ 3″ clamp of 33cm (holding the C14) ; and second the 200mm 3″ 10micron clamp holding the Esprit refractor.
Things worked out well, balancing is ok and the GM2000 does not suffer in any way. I did need to add a 10kg counterweight. This Geoptik counterweight as a built-in adapter that can be removed, bringing the axis diameter from 30 to 40mm, so I removed that adapter to fit the shaft of the GM2000 (the GM1000 has a 30mm counterweight shaft)
there is one 220V AC cable leading to the mount. All other equipment is piggy-back.
