Another comment re ball heads - while not ideal and not my preference because they weren't built for that purpose, the better ones can make fairly useable AltAz mounts for small scopes - if they are used with the stalk sideways sitting in the notch, effectively using the ball for altitude movement only. Azimuth is done by panning the whole head at the base, so it needs that function to work properly. With the stalk in the upright position, i.e. ball movement for all directions - forget it. One advantage of the ball heads I've seen in use is their smaller form factor, even of the bigger ones. If astro was the main or only use of it, I'd use something else though, perhaps a dedicated AltAz mount that connects to a standard 3/8" tripod thread.
