However long your exposure is you have an equal length duplicate while
the camera makes the dark frame exposure with the shutter closed. A 5
minute exposure followed by a 5 minute dark frame.
Meanwhile the stars have moved. Instead of trails you get dotted lines.
You can turn it off on the K10D and the K5, but not the K20D & K7 (and I
think K200D & K-x).
Don't know about the K-x, but you can turn it off with the 200D (and the
*istDS).
In that case it must be just the K20D, K7 & K-x.
I gave the night photography thing a trial with the K20D last night 7pm
to midnight. I'll find out whether I can do anything with the K20D.
Set my camera on the tripod locked down good & tight, ISO 400, manual
exposure 30sec, 16-55 @ 16mm f/5.6, remote release with 3 sec delay.
Trip the shutter with the remote and wait until the the preview popped
up on the LCD & hit the remote again. I figure that gave me an exposure
about every minute & 5 sec; about 52 frames per hour. I ended up with
about 254 frames.
I've got them downloading to my (other) computer and I still have to
figure out how I'm going to batch process the files for best effect, but
I think I'm going to see if I can put them together into one of those
little mini-movies of the stars wheeling "overhead".
