Against all expectations the clouds parted for long enough at my place to get a few shots of this event. This is the last one I got in and the one with the closest separation before the Moon started to disappear behind a roof. They did get a lot closer but too low above the horizon for me.

Nikon D7000, AF-Nikkor 300mm f/4 with 2x TC, shot at effective f/16 and 1/8s.

Cheers
Steffen.

Nice detail on the moon there Steffen - I was wondering what the dust spot on the image right was until I read the thread title :)

Great shot of the moon. What lens did you use for this?

The TC was the "Vivitar 2x Macro Focussing Converter".

Cheers

Well a TC does have some input into macro conversion of lenses.....Funny how they label it that way rather than as a Teleconverter. I would have thought they would have sold more teleconverters than macro converters with glass

Ah, but this one is actually a combination of 2x TC and variable extension tube. By extending it you can use pretty much any lens for close-ups (while losing infinity focus of course).

For shots like the one above it comes in very handing as focussing aid. Infinity focus is a difficult thing to get right with tele lenses that focus past infinity, especially if they have loose focussing rings like the 300mm f/4 AF. What I did is put the focussing ring all the way to the stop (i.e. past infinity) and lock it there, then use the much smoother and tighter ring on the TC to achieve as exact focus as possible.

Cheers
Steffen.

Forget the detail of the moon, I'm amazed you can see the Jupiter cloud swirls! Incredible!
