These pics are great.  What extension tubes do you use?  I've never worked with extension tubes before, but these pics are amazing and it's awesome that you took them with the shorty forty.

Also (and this maybe a stupid question, but like I said I have never used extension tubes) can you only use manual focus if you are using extension tubes?

There are extension tubes that allow auto focus, it keeps the electrical connections between camera and lens, and start at $ 70, and work both autofocus and image stabilizer lens. There are also inexpensive extension tubes that do not allow the electrical connection between camera and lens. Beware of them, for some lens models, specifically Canon 40mm need electricity to even do manual focus. Therefore, it is mandatory for Canon 40mm extension tube with electrical contacts, even for manual focus.

Thanks :)

I'm using the Marumi extension tube set (13+21+31). It seems like a decent quality product - metal mounts, lens electronics connection, metal lens release levers, while reasonably priced. It supports AF, which is not very usable at macro distances (just like with any other macro lens), but lens electronics support is needed to operate the manual focus of the 40STM, image stabilization, as well as aperture.

I wish I had not looked at the photos here I will be off to see my friend at the camera shop. He quoted me a few days ago and offered to order it in
Saying it may be one for his kit as well.

It also seems to be a great moonlight lens.

I like to use it with a Big hood - three times larger than the lens  ;D

Nice shot of the Pleiades!  They look larger than I would think they would be at 40mm...is this slightly cropped?
