Maximum weight on Vixen dovetail?

[rthorntn]

Hello,

Does anyone have any information on whether there is a safe weight to load on one of these bars, right now I have 18KG on it and I am worried that that's a lot of weight on 2 small meade screws and a 35mm bar...

I have a puck for Losmandy so I will probably get that dovetail regardless.

Cheers
Richard

Not sure of what the total weight is, but I use Vixen dovetails to hold my 10" newt with QSI583 camera and ST80 guidescope, finders, guidecam etc.
