 used a 2x convertor to make 800mm ... live view on the 7d will actually autofocus, hunts a lot but gets there in the end, sweet. ~1s exposed before putting a black card cap over the lens, then 136s later take the cap off and close the shutter ... simple :)

I discovered something cool when I did my moon double exposure ... using the 100-400 @ 400mm (and therefore min f/5.6) with the 2x convertor which takes the min aperture to f/11 which will therefore will not autofocus on the 7d, if it is in live view it will auto focus :) Not the fastest at focusing so not good for moving subjects but very useful for still objects. You can even zoom in on the live view and it will autofocus on that.

One other thing I noticed is how fast the moon / earth move!! at 10x zoom you can clearly see the moon moving :)

At least this sharpens your celestial abilities.

It bugs me that the two moons are not exposed to the same brightness

I presume this used covering the lens with a very long exposure time to achieve the duel exposure. The moons are well lit, but in the end the image doesn't really grab me. I would prefer (but doesn't meet the challenge) to see just the left moon, and thus the double exposure does not add to the image for me.
