I'm in the final stages of having a custom EQ mount fabricated by Gemini Instruments...we are seriously considering using the LXD55 motors as primary drives...
From my experience LXD55 is, maybe, 1/8 of the way between DS and "real" servo systems. This does not mean that they will not work fine - they are better than...
DS gear reduction ratio inside the DS unit's gearbox is 205.3333:1 In AutoStar RA or DEC Ratio number, use 0.0228148 * (worm gear tooth) ... for ... LXD55/75...
Thanks, Don't look like I an going to find that. I'll find a 200:1 and use the formula to adjust for the ratio and encoder. ... tooth) ... 180 ... post...
Is this focuser something one could use on a Schmidt Cassegrain? If so I guess it would solve the usual problems of SCT mirror shift. Lou Zyla ... best - ... ...
The only problem I see is that the telescope side is 2 inches and the EP side is 1.25 inches. If your SCT has a 2 inch EP receptacle, it should work fine....
Hi All! I broke my cable some days ago, and today after repairing it, while testing, ASU downloaded this Autostar upgrade... Does anybody know the differences...
Jeff, I have converted a number of mounts with lxd55 motors . The largest were Atlas/EQ6 , which are quite large, although probably a bit smaller than the...
Matt, Was the OTA perfectly balanced or was it deliberately imbalanced by a small amount so the RA motor was driving the OTA "uphill" and keeping backlash...
Chris, I played with the scope balance and worm meshing , backlash or tight, and basically any mount can be brought to show this lxd55 vibration. The opposite...
That is an excellent dissertation on LXD-55 motors! However in the end I am not so sure about the summary differences between an LXD-55 motor and the...
According to the readme that comes with the 32Ef.zip file on the site: Upgrades to 33Ef: Added Zip Codes. Some serial strings fixed. Am the process of...
Wonderful paper on Matt's description of LXD55 motor/servo. Custom PID is certainly possible such as MB's new servo based (SiTech), J.R.Kerr's, and many...

I have the jitter problem (DS motors) at F30 (6000mm), and if the weather ever breaks, will try using a switch bypassable 3 to 5 ohm (or maybe variable...
Greetings: I am interested in automating a Celestron C5+ mount. I figure that the PEC replaces the Drive's Phase Locked Loop drive speed controller and drive...
Modern GOTO systems with PEC do most of that but autoguiding does even better. I don't think the DEC arm of your mount has a worm gear. This means that a...
For pictures, look in the Photos section in the GP_ASGT folder. There were only two small cuts I needed to make in the plastic housing for the declination...
I also happen to know for a fact that a C5 can be mounted on the Nexstar 4 mount, which is the same as the Tasco Starguide 4 mount. The tough part is getting...
Does anybody know if I can use the RA & DEC motors that came with my CG5 mount with the AUTOSTAR, instead of having to use the motors from the DS114 mount to...
No, the motors will not be compatible. -Christopher Erickson ... From: em_91109 <em_91109@...> Date: Monday, January 3, 2005 1:02 pm Subject: [RoboScope]...
My two car garage hasn't had a car in it for 15 years - I spent most of the holliday trying to clear out a walkpath. My wife got a VW "bug" last year and...

Hi.. I've (finally) posted my patch kit here for 33Ef. This is the -2nd- edition, which corrects a serious (proc trap 2!) bug in the PEEK code of the 1st...
Thank you, Dick. When you have a few moments (hehehe), perhaps you might consider a short post discussing the recent versions of Autostar firmware, their...
