nephilim Posted April 26, 2013 Share Posted April 26, 2013 Hardly descriptive but does anyone know where i can get one of these The only bit i'm after is the aluminium nut type thing on the right hand side of the cog which loosens to allow manual slewing of the scope with the motor attached, I lost it at a dark site & have been back twice to no avail, it was in a national trust car park so chances are a small child will have picked it up cos its shiny!!

Keiran Posted April 26, 2013 Share Posted April 26, 2013 Sorry, i have no idea. May be worth contacting a few retailers and seeing what say. If not you could alway find a local machine shop and see if they can make you one. Link to comment Share on other sites More sharing options...

Keiran Posted April 26, 2013 Share Posted April 26, 2013 Can you upload a larger photo of it. Is it possible to show a photo of just the bit you are looking for? Link to comment Share on other sites More sharing options...

Keiran Posted April 26, 2013 Share Posted April 26, 2013 Looking at that it looks like a thumb nut. If you know the size of the thread inside, not sure if the diameter is important, or whether you need the cavity, but if not you can find a standard thumb nut with the right thread size on the net, and if the depth is important you can use washers to space it out.

malc-c Posted April 26, 2013 Share Posted April 26, 2013 I'm a little confused as the normal way to slew the scope is to release the clutches and manually slew the scope, but then you would upset the goto as the computer won't then know where it's pointing.On the EQ5 pro goto I had, the motors didn't have anything like that fitted. Is this a 3rd party upgrade you have fitted ? Link to comment Share on other sites More sharing options...

I think anyway Link to comment Share on other sites More sharing options...
Oily Posted April 26, 2013 Share Posted April 26, 2013 I remember someone on here asking the same question,the thread of the thumb nut is a little obscure,I tried all of my thread restorers on mine,it's not UNF,UNC or Metric so could be a machine thread?Yes Keiran the EQ5 has been fitted with dual axis motors Link to comment Share on other sites More sharing options...
Ouroboros Posted April 26, 2013 Share Posted April 26, 2013 You could try emailing your photos to teleskop express in Germany. They managed to get me a replacement black plastic knob for the manual control of the RA axis on my EQ5 mount. http://www.teleskop-express.de/shop/index.phpThe nut component you've lost is part of what the instruction manual calls the "shaft gear assembly".

nephilim Posted April 27, 2013 Author Share Posted April 27, 2013 Thanks everyone, i'll try all of the above @malc-c, as Oily & Keiran have mentioned, its the EQ5, the nut disengages the cogs on the motor drive so I can slew manually.I'll post when I have a result.Steve Link to comment Share on other sites More sharing options...

I take it that you have added the optional single / dual axis DC drive like the one belowIf that's the case then I can only suggest you contact OVL through the retailer you purchase the kit from to seek a spare. But don't hold your breath as OVL don't carry spare mirrors, so unless they have something from a return that they can cannibalize you could be waiting 6 months for a part from china. One place that might be worth contacting is Scopes N Sky's as things like this might pop up on their astroboot ( http://www.scopesnskies.com/AstroBoot ) Link to comment Share on other sites More sharing options...
Ouroboros Posted April 27, 2013 Share Posted April 27, 2013 Good suggestion, Malc-c.While we're talking about this, I do find this nut comes/drops off very easily. It also tightens up anoyingly as I manually align the mount. Link to comment Share on other sites More sharing options...
Galilean Posted April 27, 2013 Share Posted April 27, 2013 Those are the clutches - slacken them off and you can move in DEC and RA by hand. Link to comment Share on other sites More sharing options...

Steep Posted April 27, 2013 Share Posted April 27, 2013 If you find it's coming loose and dropping off, is there enough thread behind it to stick a piece of blue-tac on to? might not stop it loosening but it'll certainly keep it from falling off.

Ouroboros Posted April 27, 2013 Share Posted April 27, 2013 Well, yes ... exactly. But do you not find they tighten up when you move the dec and RA manually? Link to comment Share on other sites More sharing options...
