I recently made an altazimuth mounting to mate a Gibralter head to

A/P piers and tripods. I keep the pier outside during the winter and

have wanted a fast set-up for the traveler to evaluate the seeing and

whether there is reason to bring out a GEM and larger refractor. This

version can share the pier, balance the scope via a dove 08 and point

to the zenith. I posted some pictures to the files area:

The swinging arm actually provides smoother azimuth motion than the

Gibralter swiveling post - via a stainless axle in a bronze bushing

(under the custom socket wrench), and some teflon furniture glides

set into the underside of the arm. Threaded fasteners in the wood

provide very solid connections.



The mounting was quite stable at 200X.I watched Io occult Europa the

other night - the two moons and Io's shadow at the edge of the planet

each separated by 3 arc seconds was so beautiful that I forgot to get

out that larger scope.

Alan,



Congratulations! That's a great looking/practical set up you have

there. If and when you have time give me/us the "specs" for your

alt/az set up. I'm looking into the purchase of a wood tripod

(soon???) and very much like your alt/az mount.



Thanks & congrats!
