My 1200 pier is a piece of pipe from the junkyard. The ID was about 1/4" larger than the mount base, so I filled it with 1/8 in. al bar. The pier sits on a 15 ft dia concrete pad (with a small piece

They have portable saws that cut concrete. I'm he could get someone to cut a square hold in the concrete. He may even find someone with a saw that can cut a nice, clean, round hole in the concrete.

That will only work if you won't be walking on that floor during observing/imaging. A concrete slab is very effective at transmitting vibrations; it will act like a drum. As someone else has already

Terry: I was lucky enough to order a 1200 gto Tuesday. I believe the answer to your last question is that with go to capability, the two star alignment method will get you as close to the pole

I was allowed to place an order yesterday for the 1200 GTO mount, so I'm going over the A-P web site with a fine-toothed comb looking for other stuff I should get with it. I see that there is a

I will be taking delivery of an Astro Physics 1200 GTO mount around the end of August. It will be used in a permanent installation with a Newtonian telescope. I need a two foot high pier that will

I agree Mark. In fact, I don't use cases for transporting my 1200 mount. It would add too much weight. I simply use a heavy blanket wrapped around each axis and carefully secure in my vehicle. The

I'll second Charles. To be precise, the 1200 is more than double the weight of the 900. 80 lbs is a weight to be truly reckoned with if you have to transport the mount long distances to dark

Thanks John. Rich

Mark, Tenba makes some very nice cases for the transport of computer monitors. These might work for parts of the 1200. I know that one will hold the 900 mount as one piece quite nicely. We used it

No. I'm still looking for cases to hold my 900. I've given up on finding a case to hold the 900 in one piece. Any suggestions would be much apprecitated. Rich

Have any of you folks who have a 1200 mount found suitable cases for the 1200 head. I don't really require ATA quality cases, and would prefer to stay away from an ATA type case's weight.and

Heavy? That's what the wheels are for. They are large enough to work across a lawn. It wasn't just an adjustment issue. If you got the mesh tight enough to remove enough backlash so that the backlash

I used one of the mid-size Pelican cases for my AP 400 QMD. I have since sold that mount in favor of a 600 GTO. I shipped the mount to the buyer in the Pelican case, so I no longer have the number

My 600 GTO would stall out at 1200x with a 20-pound load, even if it was balanced. The mount came back with what sounds like heftier motors and a slower top speed (600x instead of 1200x), and works
