Hi, Does anyone know what the maximum voltage rating is for the steppers supplied with an EQ-5 mounts drive? The original drive unit uses 6v. However I want to...
There are a multitude of different Chinese factories making motor systems for CG-5/EQ-4/HEQ-5/EQ-4/etc. mounts that nobody will be able to give you an accurate...

Hi James, I use my Orion Sky View Pro's Synta motors driven by a Boxdoerfer MTS3-SDI with 19 V suply. In the MTS3-SDI it is important adjust the PWM current to...
Hi Luiz, Thanks for your reply, very helpful. Just to confirm - you mean by PWM that: If I "Full Phase drive" the Stepper so all coils are always energised ...
Hi James, See my comments in bold bellow. Regards, Luiz Giorgi Sao Paulo, SP Brazil ... In this case 500 mA is the total current to the motor (2 windings). ......
Hi Luiz, Thanks again for your help. I hadn't realised for the stepper that the total rated current was shared between the windings. Because the stepper is...
Hi James, It's me again. You are right, each winding is isolated one from another so each one have a current limit. Since I wasn't trying to build a...
I took my LXD-75 apart and polished all bearing surfaces with 1500 grit paper and WD40 and used White Lithium Grease and reassmeble. Goto's are spot on and...
... Pretty crumby foundry practice. Lots of stuff like that coming out of the PRC these days, they have a ways to go when it comes to producing small parts...
Better have the paint checked for lead and the grease checked for anti-freeze too? Some day soon some company is going to start advertising their products with...
And we would call it the Vixen GP2! Wait a minute... The all-Japanese, no-Chinese Vixen GP2 only costs $700 without a GOTO system! "My advice is free and worth...
... Yeah, but not much more than 10 years ago you could get a G11 for under 2 grand. I was making a lot more back then too, retirement income sucks in that...
Hi Luiz, Just to let you know: I did some asking around and although I didn't get a definitive answer, 200 to 300mA seems to be the ball park figure for the...
I am looking to upgrade my system. I want a mount 9(and telescope) for long duration pictures. I have a Celestron 114 GT and for even medium durations I get...
What is your budget, what kinds of objects are you working with and what kind of camera are you using? Astrophotographers always pick their mount first and...
Well, I finally did it. I couldn't pass up the Meade DSI for $99 including shipping. Now, all I have to do is find someone that has used this little jewel to...

I can't seem to find out if the Starbook S has a serial port or not. And if it does, is there an LX-200 command emulation mode. Maybe someone else can chime...
