Hi, I have a r@p focuser that is on a 8" dob. It is not working for that scope and I am changing it to another style focuser. You are welcome to it if you would like. The focuser was give to me about a year ago and So I will be passing it on to you.

Perhaps save your money and upgrade your whole telescope, you may be able to find used 1.25". Is the wobble caused by loose parts or a bent rack and pinion mechanism?
I would caution you in that there is no cure for aperture fever, once you catch it.
Heh the 150mm upgrade was just last weekend from my 114mm. I'd like to just find a decent focuser is all. The drawtube doesn't appear to be bent, and the focuser seems in tip top shape, i believe it to just be a cheap, low quality R&P focuser. My 114mm R&P celestron firstscope's focuser is better than this one on the orion. There are two little alan screws above and below the locking screw for this focuser, and while i can use those to make it wobble less, it digs into and scratches the drawtube. _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com
