Thanks, Bob. Nope, no cement table or floor. My rig is mounted on a heavy extruded aluminum base. My house has wood floor, no basement so I have to be careful when I run a stack.ummmm....................damn............. :shock: not a speck of dust to be seen. well done lad.......do you shoot on a cement table and floor?

On this set-up my effective aperture was f/21.4.Amazing. So what's the effective aperture?
I was testing an inexpensive (but very sharp) Sigma 70-300 lens to see if I could push the objective above the rated 10x.
I usually don't go past an effective aperture of f/20, but in this case it came out OK.
