Another newbie question I'm afraid.  

 

I just set up my Tristand and mounted my new Questar to it this am for the first time.  I figured I would play with the powerguide for the first time.

 

I followed the directions to the best of my ability (althought the directions were really written for the powerguide 2 and the manual that came with the powerguide 3 really just discusses the various menu options.

 

In short, after plugging the adaptors in the questar, the port on the the Powerguide 3, I was never able to detect any motion or hear anything internally that would suggest it was working.  I tried holding the x5 speed button down and still nothing.

 

Is this normal? Should you be able to detect motion in the right ascension axis. When the weather clears, I  will bring out the scope, and try to detect movement through the eyepiece.

 

Thanks.

 

Jason

With the 16mm eyepiece you have a field of view of about 1/2 degree.  360 degrees/24hours = 15 degrees per hour, or 4 minutes per degree.

 

Set to view a stationary object, it should move from the center of the field to the edge in about a minute.

 

There are discussions elsewhere about getting the right initial settings, which is likely the easily-solved problem.

 

Note that timing a transit with and without the internal Barlow engaged is a good way to determine your Barlow's magnification.  (So's viewing a ruler).

should you hear clicking or a timer mechanism when it is plugged in or should it be completely silent?

My PG-3 does make noises when it starts up. It also moves a few arc minutes and hums when the motors engage before settling.

 

Have you got the cord in the AZ jack point on the hand controller??

I  have the cord in the jack on the side of the hand controller. I believe it is unlabeled. Why would it be the az jack, when I want it to track in right ascension?  

 

I must be missing something.

Jason,

 

These may help:  They are both multi page posts.

I believe Az is the correct port.  Check the manual The Azimuth Knob controls the Right Ascension.  The Altitude Knob controls the Declination.

 

The unmarked one is for future use.

Not hearing any sound is normal. Set it up and align it on a target through any eyepiece and then come back in 10 minutes and you will see that there was motion. I had to do the same thing. Just a warning, I had plugged the cord in the wrong port on the hand control at first and when I posted a picture here, one of the members told me so. Make sure that you have the cord in the port farthest to the left on the bottom of the handcontroller. Then watch it zoom away, but don’t listen for the zoom.

What are the various options inside the PG3 controller?

Yes

I have the manual somewhere. My PG 3 works great and the cord is in the AZ Jack.

 

If Zicherja does this it should work and track in RA.

Across the bottom there are ports labeled USB, AZ, EL, AutoGuide, Encoder. The cable goes in the AZ as Kevin indicated.
