I hadn't really considered that. Beyond slowing down by 3 stops, are there other issues with the resulting images?
You'll need really good support. Use LiveView manual focus, with shutter delay and/or remote release.

I don't have the extenders yet or I'd be out testing this myself. Thanks for the idea.
You can't stack Mk III extenders on each other, unless you have a short extension tube between them. That works fine for close-in stuff, but the maximum focus distance will be within spitting range, and so shooting the moon is out. You can stack some combinations of older extenders (e.g. 2x II + 1.4x I). Optically, the 1.4x II is probably about the same as the III (I went from I to III), but the 2xIII is definitely superior to both earlier versions. You might be able to stack a 2xIII and 1.4xII, but that's a guess on my part - you should definitely not count on it until somebody can verify it, based on experience
