I have an eq3-2 mount with an Astro-tech AT80ED that I want to use the Meade controller for goto. The question I have is "How does the Meade gear (on the Meade...
They should be able to handle a 10" Newt if you use 359:1 or 360:1 worm gears. "My advice is free and worth every penny!" -Christopher Erickson Network Design...
Three complex questions in one post! 1. The DS motor housing outer threaded ring mates up with the worm assembly which has matching threads. 2. You have the...
The Retrofit FAQ is in the files section of the RoboScope group home page and there are a ton of other files, photos and links for you there to review as well....
Hi All, Just completed a successful Autostar GOTO mod to my Vixen Polaris mount but stripped the same gear in both DS motors leading to occasionally clicking...
I appreciate the input and the pointers to the Autostar-Vixen retrofit guide. I can do most of the machine work myself on my lathe, but the brackets (bottom...
Yes, I badly need to update the retrofit FAQ with the latest knowledge. I have been working on it off and on for months but still need to find the time to...
Of course brass gears would be better than plastic gears. However these are compound gears that are not generic in nature and cannot be found as an "off the...
... I think that would be great, depending on the price, but the original source referred to in the threads no longer appears to be in business. Does anyone...
The Goto4all info is a touch dated. The latest firmware in the Autostars now supports PPEC as well as autoguiding vis the RS-232 interface as well as with the...
Having just started using autoguiding on my GP retrofitted with an Autostar I agree and would go further and say that autoguiding is definitely the way to go...
Hello all, I have a pair of DS motors and an Autostar 497. I am thinking about retrofitting them to my 12-inch dob. I do not have an idea of capacity of DS...
Those new Meade Lightbridge truss dobsonians look great, but I want GOTO at low cost. Is anybody out there trying to roboscope one of them? John Boise, Idaho...
Chris, Here's an idea (possibly unworkable) that Dick may be able to help with: What about setting a custom value for "motor fault" in the Autostar? If it has...
They would make for a very interesting GOTO project! "My advice is free and worth every penny!" -Christopher Erickson Network Design Engineer 5432 E. Northern...
If using 359 or 360 tooth worm gears you shouldn't have too much problem. "My advice is free and worth every penny!" -Christopher Erickson Network Design...
We have hashed this around several times in the past but have not come up with a definitive answer. Current limiting power supplies, microswitches, shear pins,...
I agree that the mounts are interesting. Looks like Chinese clones of the Vixen GP, Sphinx and Viper. "My advice is free and worth every penny!" -Christopher...
I have not fiddled with the Autostar's PEC since unless you PARK the scope at the end of each session the data is lost in the Autostar and you have to start...
Many thanks for that, Chris. I may look into some kind of current-limiting add-on circuit to be fitted in series with the motor itself - there's a fair bit of...
Good point, Chris - I think I'll stop bothering with PEC myself since autoguiding works so well. I can imagine that it may be useful to have both going if ...
Autoguiding ALWAYS trumps PEC. PEC was developed as a way to model the periodic error on a mount and improve tracking when you don't have an autoguider setup. ...
Jim, I still have some of the brass compound gears left for the DS motors, so if anyone wants some drop me an email, quite a few members on the group have ...
Rob, I played around with this a couple of years back using polysilicon fuses but gave up when I found that the current limiting in the DS motor's own circuit ...
Hi, I have to ask if anyone knows of a good source for more metal gears? I have been lurking on this grouplately. I will soon be working on a parts list for...
