Hello, name here is Ralph.
I have a DS2114 telescope and I'm not sure if there is a problem with
either the scope controller or the operator.
Handset is a 494 with version 13Ei
I can set the time and location and Daylight Savings to Yes.
I have reset Autostar, then calibrated and trained the drives.
Unit is running on alkaline batteries, voltage is good.
I can use the 2 star alignment and then can go back and forth between 
 
them, which tells me the motors are good.
Then let's say I want to go to Orion Nebula, motors will move a little 
 
and then announce there you are and the scope is no where near where it 
 
should be. I need to try that with a power supply and see what happens.
Then I might need to enter the RA and Dec of said nebula and see what 
 
happens.
The other thing I noticed was that you can move the scope azimuth even 
 
when the nut is tight. Is there a slip clutch of some kind in there.
But the fact that I can go back and forth between the alignment stars 
 
tells me it is ok.
Any thoughts?

Hi Ralph and welcome to the Forum!

 

First off, I probably be better ask you if the mount is new and under warranty?

 

If the scope is not new, then I need to know what color it is.  If it is all black with a red band with numbers going all the way around it, then it is a generation 1 mount.  If the arm is silver, with maybe a blue band around the base or all white, it is generation 2.  This difference is important, because they made changes to fix a problem when the generation 2 mount came out.

That's a common operator error. When you bring a DSO up from the menu, the name of the DSO appears on screen - but it has NOT yet been selected as a goto target. Pressing "goto" at this point will simply move the mount to the last selected target. As it is already pointed there, the mount will just recenter the current target just as you describe. You must press "enter" again to select he target. Then a goto will move the mount to that object.

Thanks, Mr. Crilly, for pointing out the easy thing first that I ran right past.

Thanks for the welcome, Bill. Mine is the second generation mount. It is about one and a half years old.

I am assuming there is a way for the mount to slip yet be firm enough to track.

Not having issues going back and forth. The other gentlemen pointed out that it could be operator error.

I agree, I do not take the scope out enough. I plan on that now that I joined a local astronomy club.

Will keep working with it and I know where to turn for answers.

Ralph

Thanks, Ralph!  I certainly hope Mr. Crilly's answer is the right one.  The generation 2 mounts are really pretty robust and very little happens to them.  If it is not an operator issue, then what you are experiencing is really rare and will certainly tax my abilities to figure out what is going on.  I do reasonably well with mechanical issues, but have no real idea about electrical or programming ones.

 

Hope it all works out well for you!
