Hi Brian and welcome to the group.
You can buy a proper alt/az telescope mount from Andrews Comms called the AZ-3. This mount is specifically designed for the job at hand. The mount is manufactured by Synta in China and is a clone of the precision Vixen Custom D, Alt AZ mount, which I believe is no longer available. The Synta AZ-3 has a few minor balancing issues out of the box but can be easily modified to work well. Here are some articles on modifying it.
