Dunno Laurie, I haven't got any bathroom scales.
But it is very heavy!!!! And that is only the head and motor drive. To be added onto it there is also the 2 car wheel hubs, RA axis mount & counterweight bar, the RA axis adjustment mechanism, the counterweights, the pier, the legs, the scope cradle, the 12"scope, and the illuminated Guidescope!
All up I imagine about . . . 3 tons!
