Thanks to everyone who took a peek and/or left comments. Looks like at least some of you liked it... :-)
To Mark Roberts: Maybe two hours is as expected, I don't know. What I do know is that adding noise reduction brings you down to two exposures per battery, in ambient temperatures around 10° C. That doesn't look good for the winter season, and feels a bit unpractical. Makes me consider looking for some kind of external power source. The K-5 performs better. The fewer pixels makes a difference, I suppose. Btw, I've noticed that the 645D seems to draw less power in "B" mode when using the IR remote than when using a cabled remote. That surprised me... None of the half-hour exposures made it to the blog. The last shot is the longest, at ~15 minutes. The first and the second last are ~8 min. The others are more comfortably short. To Bob S.: Yes, I suppose the asphalt on the bridge gets a glazing every now and then. It will be sanded when that happens.
