Anyone know what species this is, and is it supposed to be common in southern Finland?
Shot with my 17-40/4L zoom lens and a 21mm extension tube. Depth of focus is minimal.

Finnish MicroMagic nationals
With a boat that had been assembled only three days before the event I sailed in the Finnish MicroMagic nationals that were held over the weekend in Tampere. 14 skippers is ok-ish, but with 70 registered boats I had hoped for an even bigger fleet.

Lunar time-lapse
117 frames taken 1 minute apart with 1/20s exposure through a 40mm F/5.6 lens, iso100. Shot between ca 1am and 3am early morning on Thursday 16 July 2009.
I've also combined all the images into one, using either all (1 minute interval) or some (2 and 3 minutes) of the frames:
This is clearly worth doing again when the skies are darker, perhaps with a longer focal length lens. The back-drop of stars and planets would be nice to catch also, but because the moon is very bright and the stars much fainter that will requires some HDR-magic. For a long HDR time-lapse series I would probably need a programmable intervalometer (e.g. netbook w. USB-connection to camera).
MicroMagic, FIN-70
I got my MicroMagic assembled and sailing three days before the big race which is in Tampere on the weekend.
Flowers etc.

Adobe probably wants to say something like "close download-wizard", but they've translated this into "near download-chief" 🙂
4-Cell GP Recyko battery packs
There is a new generation of low self-discharge NiMH batteries out there, GP calls them Recyko and the Sanyos are called Eneloop. I put together two 4-cell packs for use in the MicroMagic. These have a nominal capacity of 2050 mAh - I will post later some results of discharge tests. Weight seems to be around 125 grams including some epoxy that holds the cells together, the heatshrink tube, and wires with Deans micro plugs.
