Help tuning up a CG5
Posted 26 January 2013 - 08:58 PM
First, the power switch isn't working. I could de-solder the switch, and solder a new one in place (if I can find a matching switch). Or I could just put a jumper across the switch, and use it without a power switch. BUT I was wondering if anyone had any suggestion on how to recondition a slide switch that isn't working? I don't know if a spray with WD40 or something else might do the trick... Any suggestions?
Second, there seems to be a lot of play in there RA axis. I haven't opened it up to see what's inside yet, but I was wondering what I should be looking for when I do?
Lastly, it needs a polar alignment scope. Where can I get one, and how much should it cost?

The play in the RA axis is probably just the wormgear/ringrear adjustment. This can be done when you have the motor cover off.
With the "All Star" polar alignment routine in the HC you don't need a polar scope. The firmware version is faster and more accurate.

How much is "a lot"?
The polar scope is pretty much worthless. The AllStar routine in the HC will produce a better polar alignment.

The Astronomy Boy web site has a whole section on tuning up and adjusting the CG5 style mounts.
