The LXD55 mount head is, in my opinion, superior to the Celestron/Synta CG-5. At least it uses brass for bearing surfaces rather than the housing's alloy. It...
This is a little parochial ...but I use 5 ways belts and bearings from Essex. I bought a 24 foot length of 1/2" pitch to drive the inside of the dome and two...
Hi All, just thinking, is there a schematic diagram for a "simple" servo dual axis drive? I was thinking of making one. It is hard to get the LXD75 motors, and...
Hi I don't have any actual diagrams but if you are just using servo motors and not interested in a goto type of system then it's really quite simple as all you...
Hi Peter, I think drive it without motion feedback, pure dc regulator just not enough. I know the Jaycar motors. My idea is to design with the optical...
I would be interested in that myself. But I would also want high speed slewing. Doug ... -- A good day to Golf is a better day to Fish [Non-text portions of...
I don' think you will be able to get accurate sky tracking using servos/PWM unless you set up a closed feedback loop via axis optical encoders. That makes...
Hi Everyone: I am told this is the place if you have Celestron goto stuff. Presently, I am trying to move the guts of a 114gt onto a meade 2080 gem to convert...
One of the reasons the Meade Autostar system is so adaptable that changing the ratios is very straight forward. Generally the Nexstar system does not share tht...
George: Thanks once again for your amazing input. My controller has the two star option so it is no doubt not the one you referred to. I have not actually...
Hi Mick SO what you want is a drive system that can be set-up for computer control or some form of pointer system that will remember how many steps you have ...
No, I don't want go-to. There is plenty of options for that. I just like to have good tracking, with perhaps 2 speed for correction. The idea is to make it...
HI there Miki, I don't know if this would help, But model trains have micro chips for motor control and they can be configured for most D.C. motors. They also...
Miki, foregot to add some chips are R.C chips. Jack miki63au <msz@...> wrote: No, I don't want go-to. There is plenty of options for that. I just like...
Hi Jack, thanks for the tip. I don't know enough about the model controllers. I assume the feedback is position sensor pot. I don't know if that accurate...
The problem with servos (and DC motors driven by PWM) is that without axis encoder feedback, any kind of accurate tracking will be effectively impossible. Of...
Hi Miki, It's all digital PWM . Most have a 126 speed steps and and a programable curve. Jack miki63au <msz@...> wrote: Hi Jack, thanks for the tip. I...
... 126 speed steps corresponds to a 7-bit command word. Compare to the Autostar's communication with the DS motor cards, which uses a 24 bit (6 million speed...
Hi Mike, If you're just after a 2-speed controller on the cheap I'd suggest being on the lookout for one of the original non-GOTO EQ6 or HEQ5 controllers and...

I purchased one of these sets from Telescope Warehouse, and I have to say it was a pleasure doing business with them. Shipping was fast, great communication,...
Peter, a dc motor will not run in a constant speed unless you control it. Back in the old days Meade had the LX10 with dc motor and only a linear regulator. It...
