Ron, You are full of good ideas and your explanations are very clear (looking for a technical writer/customer service job?). The side bolts on the 600E mount are M12x1.75P. An alternate supplier is

OK, hello, to answer your questions regarding the safe zone, and also I will place this into the group area so that others may also use the information if they find it usefull 1) Orion below the

Hello again , Mike. I use a pier and have never had the scope hit the pier. Set your slew or pier stop number to #3....it will handle problems annd you will be able to go to the zenith. You must be

Hi Marc, Congratulations on your new mount. I had a 400 QMD for several years and they are very easy and quick to set up. There are several ways to achieve alignment good enough for observation.

Hi, Just a simple question from a novice. I placed my name on the list for a 400 mount thinking it would be way in the future. Well the future came quickly, and the mount is due in the next few

Hi Howard, Whoops, I just realized the values for longitude and latitude were reversed - I've corrected it to long W 79:24, lat N 43:52 (I copied the info from my LX200 manual where the order is

Hi Howard, 1) yes long W 43:52, lat N 79:24 2) yes time zone 5, DS 0 but I double checked the time and it was one hour advanced. This could account for the horizon problem. 3) yes, polar alignment

Hi Mike; First do you have the correct long. and lat. settings.??? Second do you have the correct time zone/ daylight or standard. Third did you do a polar alignment and did you start off with a

Hi Paul, IMHO, this is a problem with the way the shaft was made. You shouldn't have to put the weights on from the threaded end of the shaft. And, you shouldn't have screw the shaft into the mount

Hi Derek - Thanks for the note. The pin isn't the problem, the shaft actually does get wider at the end opposite the threads. I tried the following a few times earlier this morning. When I put the

Paul said: I said: Sorry Paul, I didn't get your second post until now. If you can't slide the counterweight down the shaft and the screw is out, then perhaps the pin is stuck or maybe you really

Paul: I agree with what Eric said below. Sometimes, I have to gently push the pin down, even when the counterweight screw is in the "out" position. If you look through the counterweight and turn it

Egad! That doesn't seem like a practical thing to do. I always put the cw bar on first then attach the weights by sliding onto the shaft. So what this implies that is that you have to load the shaft

Hi Paul, You did get it to work... but you also uncovered a flaw in the counterweight shaft. You should have a shaft with a uniform diameter and you should have no difficulty adding or removing

Hi Paul: I have only had my 900 GTO for a little over a week and only had a chance to use it once but have a suggestion for you. I thread the counterweight shaft on first, then slide the

Hello everybody, I've just joined and I find these postings useful and informative. I hope I can find help for some questions: I have an AP155 EDFS with piggybacked Tak FSQ106 on a pier

Hi Rich - Thanks for your note. That wasn't the problem, but I did figure it out this morning (my initial theory of it being a stupid question was pretty spot on!). My mistake was trying to put the

Are you sure you have the set screw backed out all the way? There is bronze "nose" that "floats" in the hole. I always slide the weight on the shaft with the knob on the weight pointing down so that
