Nobody ever complains that their mounts are too stable. Many people complain that their mounts wobble or don't track as well as they expect. Many (if not most) high end images that you see in astronomy magazines have been taken from a telescope mounted on an EQ6 - one of the best value and strongest mounts available to amateur astronomers (without spending silly money on super-high end mounting systems).
Well, this is not the EQ6, it's the HEQ5 and...
1. It's just like the EQ6. 2. It has the same pointing and tracking accuracy as the EQ6. 3. It's just smaller and lighter.
The legs on the HEQ5 are thinner and the mount carries about half as much. It's enough for a big Newtonian for a visual observer or right at it's limit, an 8" Newtonian with a 3" guide scope, plus a camera.
Whilst the EQ6 carries more, it is very heavy. The HEQ5 is much lighter so, in my opinion, it works out the better deal for those of us who have to carry it outdoors and set up before use and pack away at the end.
It's easy to use, has an illuminated polar scope, and does everything the higher end mounts do for less money and less weight.
The only downside is that it cannot carry the heaviest payloads for imaging, but I suspect that for most people it is just fine. (More than fine, it's bloomin' brilliant!)
