Motorized CG4 Question
Posted 06 March 2013 - 01:47 PM
1. Will I have to use the motors to move the scope in RA and DEC (I know I would have to to maintain polar alignment), or can I slew it (in DEC) by releasing the clutches. My understanding is that I have to use the motor in RA, there is no "manual" method.
2. The motors use a 6V battery pack (4 "D" batteries). I have a 6V 750ma power converter (- is the inside of the plug, + for outer side of the plug, but can be reversed). Which is the proper polarity setup for the power converter for use with the motors (instead of using the battery pack).
3. Any other power recommendations--Note this is a 6V, not 12V system...

BTW are you planning on doing AP? If not you may find that the DEC motor is of little use with decent polar alignment. If this is the case you might consider removing the DEC motor and re-attaching the DEC slow-mo cable. That is why I got the RA motor only.
Also I have found that the batteries last quite a long time in particular when you minimize slewing with the motors. If the scope is well balanced at the beginning you can slew by hand to a target and it will not move while you tighten the clutches thus minimizing motor slewing. But I do carry around an extra 4-pack of batteries although when the batteries run low it is the slewing by motor that is more effected then the tracking itself.

I keep the scope balanced, but have not even put the scope on the mount since the motors were installed (The scope shop installed them for me, and I know they do good work).
I have marked the dovetail with the balance point, that shouldn't change with the motors.
The lady told me I lost the RA, and I just misunderstood her to mean I had to use the motors. Good to know I can still slew it around manually.
