Can anybody confirm that 4.10667 is the correct ratio for a ds motor connected directly to the worm shafts on an EQ6 mount. (not connected by the original...
You can NEVER rule out motor noise. Changes in cable lengths and metal enclosures can effect vulnerability to motor noise. 4.10667 looks right for 180:1 worms....
I have a set of LXD55 motors as well as an autostar 497 controler that i could be convinced to sell for what it would take to replace them today. Regards Chris...
Thanks Christopher, Peter and Mark for your replies. the weird thing it did, (and this is when I gave up and unplugged it) the dec axis did over 360 degrees...
The model 494 Autostar when connect with EQ motors (not DS motors) understand that is connect at this type of motors and set the type of telescope into EQ114...
It's wrong. I believe that the code for Alt/Az or Polar is specific to each 494. I have one from an EQ114 and it runs in Polar mode on either type of motor...
Mark y Roberto, greetings. Mark is right about upgrading to a 495 or 497.. the flexibilty is well worth the trouble. However, Roberto, the 494 handsets -DO-...
A 495 and a 497 are essentially the same thing. The only difference is the firmware version. So if you update a 495 with the current firmware then voilá you...
They don't until you do a firmware download to the 495 to turn it into a 497. The 494's have a smaller database and can't be upgraded. Interestingly, the 494...
this is being offered on ebay for $45. does anybody else know if it is cheaper elsewhere? also, the #497 controllers are about $100. same question. thanks, v...

As you may have read, in some of my past posts, I'm interested in adapting the DS motors (and 497 Autostar) to drive my 16" DOB. To this end, I have spent many...
$45 is about right for the 492 setup. It should include 2 motor assemblies, hardware, a simple control paddle, a battery holder, and a plug panel. That's the...
You have the right idea Bill. But consider that the gearbox is also of the "toy" level. That's why several people have replaced the whole unit, and just...

Doh! Now you've done it. People are gonna start asking what the "Kennel" is. You're gonna get your membership card revoked and then we are gonna have to change...
Hi everyone, Does anyone know the tooth count on the main RA gear on these mounts? I'm asking because I'm using the RA drive+corrector made for an EQ3 on my...
Gday, A mate mentioned that somewhere hidden on this group were plans for making an IP to serial converter. I have a goto system that uses serial port...
hi, just an idea, but perhaps you can use one of those printer server devices that sits on a network and supports parallel or serial printers. i guess then you...
Check out www.microchip.com. They sell microcontrollers, and several of the designs will act as a TCP/IP device with serial outputs. Schematics are simple and...
I am considering purchasing a Mead 4504 Goto scope for the mount. I have a Skywatcher P1145 reflector on a on EQ1 mount. Need I say more. A few questions: 1....
