Aaaw..thanks all
I'm feeling a bit nervous but I'm sure all will be well. nice to get some well wishes too - it makes me feel tons better.
Chris - that site of yours is great. OH is very interested in parasitoids and insects in general as photographic subjects. He's collecting a few at the moment for very detailed image studies involving 30 - 40 image stacks . Not quite microscope work yet but between 10mm and 60mm on bellows and focus rack etc.
Cheers all!
