Mount for an Intes MK 67 Mak-Cass
Posted 25 August 2009 - 10:22 AM
One mount that was suggested in the Astro-Tech Voyager. Another I am considering would be a UA Macrostar on an Oberwerk surveyor tripod. And of course I would consider any other suggestions.
For a GEM, if I go that route, I am considering the LXD75 or the Celestron/Orion/Skyview CG5.
I'd be interested in hearing first whether an Alt-Az or GEM would be better, and then any specific suggestions. Bonus points for any mounts that would match the neo-Stalinist design ethic of this scope. Thanks!

Iâ€™ve used mine on both alt-az and German equatorial and it would be tough for me to choose one over the other given that I use the â€˜scope for deep sky as much as for solar system items (not that I use the â€˜scope that much nowadays - see sig). With your stated priorities I think I would go for the gem.
The Orion SkyView Pro handles the MK67 well for light-medium visual use (forget it for imaging or for advanced hard-core observing/sketching). Tracking is a real boon for long duration high magnification views, and the (non-extended) mount generally puts the eyepiece at a comfortable height for sitting. The whole thing can be picked up and moved a fair distance by a fit adult of average build. Thereâ€™s a knack to positioning, but once you get it itâ€™s just a question of leaning sideways a bit with the complex pivoted slightly on your hip whilst raised a few inches off the ground (axes locked!). The mount is cheap, easy to set up and pretty durable.
For alt-az I use a Tele-Optik GiroII (on a lightweight wooden surveying tripod). Usually there is an ED80 refractor on the other side for widefield scanning and balance. Although the mount can handle the MK67 by itself in terms of smooth axial movements, the centre of gravity is a bit worryingly lopsided (one clumsy lapse of concentration and itâ€™s over). Lots of DSOs have been eaten up by the MK67 on this mount (itâ€™s surprising good in this role), which makes sense because the GiroII enables both quick-and-easy slews to new selections and smooth and easy manual tracking once youâ€™re there. I find tracking planets at high mags quite easy too, but I certainly wouldnâ€™t want to spend all night doing it. Again it is possible to move in one go but is actually more difficult (v. top heavy with my tripod).
The pic is just after I got the Orion mount (a s/h bargain) so only one counterweight and no motor. Gives an idea, though. Sorry, no pic of MK on GiroII.
