Counterweight help new
      #5517761 - 11/13/12 11:45 AM

I purchased a Nexstar 11gps this summer with the celestron counterweight system #94192. Since then, I've upgraded the diagonal. and have been using 2" eps, which have been giving some balance issues. Now, after using a ff/fr and my Nikon D700 for imaging tests, I'm finding the 2.5lb weight a little on the light side. Unfortunately, Celestron has discontinued that cw system. Does anyone here know of any weights compatible with this system, or or should I just suck it up and order a whole new cw system?

Ummm, okay, this is embarrassing. Literally 30 seconds after I posted this, I tried another search. I found one on Amazon, it showed what looked like a 22lb cw, but stated it was 2.5 and had the right #'s. After I placed my order, I went to double check, and it said there were no more available. Looks like I grabbed the last one. Lucky me!

Should that not work out, and assuming that the Celestron counterweight system is similar to the Losmandy one with a screw-on 2.5 pound weight, you might try what I found to be a simple low-cost solution. First, screw a large nut with a wide washer onto the spindle. Next go to a sporting goods store and get the small 2.5 pound weights for barbells (as many as you require -- they cost about three bucks!) Then slide it on and screw the original threaded counterweight on the spindle, tightening it below and the nut/washer above to secure the new weight.

Wow, at that price I'd dump the whole thing and go with the ADM solution. That's what I use on both my C11s and it works great. It's about 40% less and has a much more robust Vixen rail system. You could add two additional counterweights (although I never use my second one) and still end up costing less. Just a thought...

Beo

I actually installed the Starizona counterweight system on my CPC 1100 two years ago. It is pricey but it works as promised. I can load up the viewing end with heavy denkmeier binoviewer and eyepieces. Then adjust the counterweights on the rail to take all the load off the altitude clutch. I think this will extend its life considerably and that would be worth it to me.

If you know someone who has a metal lathe, why not get a bit of lead round bar about the right diam and have them make you suitable (very compact !!! cf the steel ones sold by the OEMs) mass counterweight.

Add a bit enamel paint to the outside and it'll look great and be a very cost effective solution.
