It locks onto the back of the lens itself fine, but then of course the 2X will not connect to the back of the 1.4x because of the design. Has anyone else had this problem? Mr. the Kid.

It appears the black plastic ring around the edge of the TC that competes the weather sealing with the lens fell out at some point, and the previous owner tried to put it back in, but did so backwards so it was not flush with the rest of the lens, I took it back out and put it in the other way, it went in flush, and voila, everything works as advertised. Mr. the Kid.

I also took an image of the moon without the TC's, and put it directly into the other file for an exact size comparison:  1400mm vs 500mm by HiAperture, on FlickrMr. the Kid.

I find it tricky to get decent shots..even of just the moon, when stacking.
