How long do you need to track for? Dawn to dusk tracking with some designs
of equatorial mount can be a problem depending on the size and weight of the
instrument, due to clashing of the mount with the support. A fork mount
might be a better option eg

Your best bet may be to find your local astronomy society who will no doubt
be glad to demonstrate what is available
