pushing the limits! I think this is about 46 pounds of stuff on the 12 inch

this was another challenge..... an AT 8 inch f/4 riding piggy back on the classic LX 200 12 inch..
the weights tell the story, 23 pounds on an ADM mini dovetail.... moved away to match the CM of the AT, also about 23 pounds
including the 350d outboard, and the weight of the farpoint dovetails set, etc, and the total extra load on the forks is just about 46 pounds...
the two chunkc of iron on the right fork are to balance the camera .... East preload is about 4 ounces over the 90 degree window..

and, it still guides pretty well.
