pointing screw ups...

I don't have a gemini but have the following to offer:



1. Observing on a rug is good on asphalt, protects dropped eyepieces

and gives the mount something to dig into. It can actually increase

pointing accuracy.



2. Putting the same system on the grass is a disaster. The rug is

like a snowshoe lifting the mount above the grass and the rocking

will destroy accuracy.



3. I thought myself a clever lad to have gotten hand-knobbed bolts

to connect the head to the tripod base but last night was able to

confirm that no matter how much I tried I couldn't get them to be

tight enough to prevent some rocking of the equatorial head. I had

to go back to the old screws. I just couldn't apply enough torque to

the handles to get the thing to stay put. I think the C14 puts

considerably more stress on the mount than the 9.25 in this respect.



regards,



Greg Nowell
