I disagree. Dangerous? LOL There's hardly any cross section in it - so wind isn't really a factor - I don't image in gale conditions. The bar is balanced remember - that's the whole point. It's easier on the gearing - not harder. If I knock it I'd stuff my image more than the unit. I have never knocked a telescope imaging rig in as long as I've been doing it as far as I can remember.
Not really concerned... unless a kid at a public night decided to hang off it.
In reference to the weight being kept close to the RA axis, it's not - even with a short ball head mechanism. Loosen off the thumb screws and just see how much twisting moment there really is when the camera rig is at 3:00 or 9:00 o'clock - it's incredible. With this, I can loosen both thumbscrews and the whole thing just hangs there - not exerting any rotational force.
