Hypothetically speaking, how would AZ3/AZ4 fair against EQ2/EQ3? Of course the later can be polar aligned for ease of tracking. But discounting that, and considering dampening time, stability, balance etc for visual use only. For a small refractor under 90mm.

Ideally all things should be considered equal, the mount you use for visual should be just as steady as the mount you use for photography, or else its gonna shake every time you put your eye on the ep, and who wants to look through a jiggly scope, but you should be fine with with a 90mm on one of those at low to med powers, but high power it might be a little shaky, specially if it has a long f/L. some individual mounts of the same make and model can vary in stability, and should also be considered. if you can, try before you buy and use high power or the power you mostly use when trying to judge stability.

I would never recommend an AZ3 for astronomy use.

These are great for terrestrial, but horrible for the sky.

If you set the tension screw for azimuth to make the scope smooth to move, when you tip the scope back to view near zenith, it will cascade on you. If you set the nut tight enough to keep it from cascading, it will be so stiff that it is hard to move when re-pointing.

Horrible for astronomy. OK for terrestrial use.

Otherwise, I realize the question is hypothetical, but none of these mounts are all that great.

For astronomy though, the AZ3 is simply inferior to the small GEMs.


And if you don't need tracking and the scope is light, I think the AZ4 might be OK.

The GEMs you mention usually don't come with dovetails and these days, that is the only way I would mount a telescope.

Maybe they have some with dovetail saddles now though, but for me, I would not own one if it did not allow for quick mounting/unmounting.

So, AZ4 if you made me pick from these and I did not care about tracking (though I just can't hardly use a telescope if it does not track)

Since your question seems to accept non-tracking is equal though, I would think the AZ4 would be the best of these.

I think you could get a better GEM used here on CN for not much more money. Wouldn't expect much out do a new mount that was $150. For your 80mm refractor it may work out. There is an LXD55 for sale now for $155. Now, the LXD55 isn't a great GEM but I'd bet it is better than the one you linked to.

I would save a little more money and just get the Celestron Omni CG4, its a well built and good looking mount but I think that if you have a 80mm F5(400mm) or F6(480mm) length refractor it would work on the eq3

have you tried the classifieds here on CN, you can find better used mounts than that eq3, just like the other poster mentioned

There's a Super Polaris on the classifieds (or was it on astromart) for $150.

In other words PLEASE DO NOT GET THE EQ3, if you get that, when you want to get a little larger telescope you'll have to get a bigger mount anyway, so save yourself the money and frustration of using a shaky mount and get something decent, so just stay away from those and you'll be fine.
