This mount was part of the Konus Motormax 150 setup and the mount designation is EM-10 (it is NOT a Tak EM-10, however). It has a polar alignment scope as well as dual axis drive and a hand controller. It also comes with a tubular steel, extendable tripod. Furthermore, I had the Konus people go over the mount, lube it and make sure the wiring for the motors is correct...in other words, they did a complete quality control inspection. I have read some people claim it is rated at 30 lbs. but I personally feel 10 lbs. or so is more like it. It's very well made and has similar specs as a CG5, although it isn't a CG5 clone. If you're looking for a medium duty eq mount that's fully equipped, this is a good choice. The only reason I'm selling this is because I already own a GM-8 mount! Only $250.00 + $25.00 shipping, although I'm willing to drive a reasonable distance in Northern California for an interested buyer. Thanks for looking!
