Originally posted by AZGMDale Very nice! Did you, or have you, tried the "ASTROTRACER" mode on a shot like this? Does it work on the moon as well?
First of all, if the moon moves enough to blur its detail, then moving the sensor to remove this blur will simply transfer the blur to the buildings, which will now appear to the sensor as if they are moving against the sky. It's similar to panning, where you can unblur one motion at the expense of introducing another.
Regarding the moon itself and astrotracer: The "motion" of the stars appears because we're viewing the sky from the rotating surface of the earth. The position of the moon is subject to the same effect, so, yes, to the extent that astrotracer compensates for the diurnal spinning of the earth, it should also work for the moon, and even planets, if you're interested in those.
However, since the moon is moving around the earth once a month, it does move extremely slowly against the background of the starts on a much longer monthly basis, and this version of astrotracer will not compensate for that. Given the notoriously high resolution of the K-1, this lunar motion might cause blurring of the moon's surface on very long exposures, so hopefully, Ricoh's next firmware release will have 2 astrotracer settings, the current one which follows the stars, and a second slightly different one to follow the moon's monthly orbit superimposed on the stellar background. Presumably, the K-1 can determine astro time from satellite measurements, so timing of the lunar cycle and the moon's position will be computed automatically, and a new set of graticules can be provided to locate individual craters in the viewfinder, whose names will be accessible in a new moon menu. Perhaps there's already an iPhone app for that, which Ricoh could incorporate into their WiFi...
To cut short unintended arguments, the entire last paragraph was a lame attempt at weird geek humor.
