A favourite subject, revisited at an "adult pond dipping" I ran at my local nature reserve. We brought samples back to the visitors' centre and I was able to display live microscope images on a large TV screen used as a monitor. This one caused a few gasps from the assembled group (I've tidied up the background and rebalanced the colour):
Microscope: Zeiss Standard
Ocular: Zeiss KPL-W 10/18
Objective: Zeiss 1.6/0.03 - 5/0.1
Substage: Leitz 0.9 NA ICT, top flipped out, pol only (no DIC prism), retardation filter.
Specimen: live, anaesthetised/lidocaine
Warnham LNR, Horsham, UK, 19-Jul-2011
Sorry, no scale bar: there wasn't time to calibrate, but Chaoborus is a few mm long.

Very nice and unusual image. Pol or DIC/Pol is a great way to show up muscles in transparent specimens as they are highly birefringent. I like the colours in this one too. That variable zoom low power objective is a useful bit of kit.

Wow, it seems there's a funky laser light show going on inside that beastie!  
Great capture, Graham!
