Hi Peter, Many thanks for correcting me on that! Do you (or anyone else) know how many RA and DEC teeth the Meade scopes which the simple 492 hand unit was...
Thanks, Geo. As I said in the original post, I'm currently using it as a pan and tilt controller (on an EQ3-2 set to 90 degrees) for ordinary daytime video and...
Hi, Rob, Both the gears that came with the #492 DS kit have 60 teeth. It's safe to assume that is the preset in the 492 handset that comes with the kit - the...
Hi Peter, Just what I was after! I can source pulleys/toothed belts and can knock-up a suitable bracket/housing, so just a case of finding the right pairing. ...

Thank you. I took a look at the destructions in the ETX manual. Never realized the EC was this capable. Here's what's there: "The Electronic Controller...
... The ETX90/105/125 and the very early 70s use the same gear and worm ratios. The worm wheels are interchangible. So sidereal should be the same. I see from...
There is a group that does iOptron on Yahoo. Most motor control for robotics and industrial apps is by push-pull circuits with a microprocessor used. Doubt...
Thanks George The Part I am chasing is the actual motor drive chips, in the GOTONOVA there are two chips one is a Duel N-Channel Mosfet and the other one is...
Pretty interesting chip. It has pretty high current rating - 30 amps drain when pulsed. Supposed to be OK up to 155degC. The data sheet indicates it will...
Hi guys I'm just about to take delivery of a GPDX with dual MT1 motors & a DD1 handbox. Could anyone tell me what my best goto options are? (poss I should just...
The MT-1 motors are only useful for the Vixen single and dual axis non-GOTO controllers. The Vixen SS2K GOTO controllers need MT-2, MT-3 or MT-4 motors. Your...
Hi Christopher Ok. It's prob an Autostar retrofit when I find a used LXD. Thanks for the input Leigh www.cathouse9.freeserve.co.uk ... From: Christopher...
Sometime ago, I read that the position of the DEC motor was such that with the mount pointing polaris the motor shall be to the east. Mine is that way and it...
It should work the same with the motor on either side. The importance of the side has everything to do with avoiding mount crashes. Double-check the numerical...
... Hi George Unfortunately I'm in England & the postage is coming up @ $200 :o), however, I'll keep my eye on it Obviously we're 240 volt over here. Do u...
The mount runs on 12VDC so all you will have to do is come up with a 240VAC to 12VDC/2A power adapter. Or use batteries. And all you really want are the two...
There are several 3rd-party controllers that will drive the MT1s and give you full GOTO. I use a WinCTC on my GP/DX, which is permanently mounted in my...
Hi Rob Yeah, I've looked at a few controllers but the ones I've looked @ for MT1s have all been quite expensive and now you've highlighted the low slewing...
We just sold our LXD55 for £120 on eBay - sorry you missed it, but it seemed a fair price for us as we upgraded to the LXD75. Cheers, Niall Saunders Clinterty...
The drives and such would ship for about $30. G. ... however, I'll keep my eye on it ... differently or is ther aw way of setting input voltage in the handbox?...
... Hiya George Maybe if I won the auction u could send me the Autostar and keep the mount. I'd only strip it and resell it anyway. I see it's ramping up...
