Celestron CG5 mount
I wanted the CG5 for a 4" refractor. I was expecting something shaky and was pleased to find a pretty sturdy GOTO mount. My refractor weighs 6 lbs. This mount is rated for 30 lbs of instrument and 33 lbs of weights. Read the manual several times to learn about features. If you have any experience with computorized mounts, this one is a snap to learn. The one tricky thing I found was that upon power up, you needed to push the undo button to get to the setup location menu when prompted to do a 2 star alignment, (the default screen that comes up upon power on) I used a GPS to get my location, or ...

Review for CG-5 GOTO mount
Assembly and set up of the CG-5 mount and the tripod are straightforward and quick as long as the instructions are followed. The RA and DEC clutches must be locked for the motors to move the telescope properly, an important point that is not explicit in the set up instructions. It takes about two trips to load the mount to my car for field use --- so it is a portable mount.
The dovetail clamp secures the equipment on Vixen-type dovetail with two screws. The clamp holds the dovetail secure, and I feel confident that 13lb (or several thousands dollars) of my equipment will not slip off the mount. However, the construction of the dovetail clamp is awkward since the sharp ends of the screws in the clamp, when tightened, easily damage the aluminum dovetail of my optical tube. While this damage is cosmetic rather than functional, and aluminum is a soft metal, one could imagine that Celestron could and should have done better.
Polar alignment of the mount is quite easy even in darkness. The Celestrons alignment routines are straightforward to use and result in a good polar alignment for visual or video use at least. I center Polaris in the hole along the polar axis first, then follow the two-star alignment routine, add four calibration stars, and run polar alignment routine to align the polar axis to the north celestial pole.
After the mount is polar-aligned, and the two-star alignment is completed and calibration stars are added once again, the mounts performance is ...
