Quote:Nice!! Be sure to post up a review after you've used it. I am interested in hearing your comments. At some point I have to add tracking to my dob - not expecting delivery until July though.

Quote:The biggest drawback to platforms in my opinion is the weight when it comes to one big enough for a 25" scope....Most weigh in the 50 to 70lb range that I have seen.This one?.....shipping weight was 22lbs.....While I have yet to put my scope on it I can tell it should should hold my 20 very well without groaning.....I was going to get a servocat because of the bulk and weight of what was available even though goto doesnt excite me. Then Alvin posted about Gregg's new design and it was off to the races for me.

Quote:What's The point of having tracking platform?Just buy servocat and you will be happy.nice job though.
Quote:I think Push-To is actually better than Go-To because there are less things that go "break" in the night. The less things to go wrong, the better. Plus the low battery consumption of a platform and simple Push-To DSCs. No need to have heavy lead-acid batteries and recharge everything daily at a Star Party.
Quote:I am with you Gregg.... I find I spend more time observing and less time waiting for the goto to actually goto also.

Quote:GShaffer: I would love to see some pictures. I also ordered a EQ platform from Gregg and plan to put my GB on top of it so I can retain my goto (the GB is round and the azimuth motor drives on the outside edge if the GB). My platform is supposed to arrive tomorrow.My plan was to get a plywood sheet about the size of my GB and make cutouts for my GB feet and bolt it to the platform using the pad bolt holes. Then I could back my scope onto the platform as you do.My plans have be made in the absence of the actual platform, so I may have to modify them for the actual hardware...
Quote:I used wheelbarrow handles with my platform and set it up so the wheels are at a height that made the scope the same height as the platform pads when the scope was held level. Then I would go around to the north end of the platform and move it over from north to south until it was over the center bolt.
