what color bands are you referring to? I didn't notice any.
Horizontal or vertical? In any picture in particular, or in all of them?

mostly at 30 seconds and at f/1.8.

Has pentax changed the long shutter noise reduction? I've got it
set to default (1 in the menu, use when needed) and it doesn't seem
to be kicking in. My 30 second exposures only seem to take 30
seconds, not a whole minute.
Also, there's something that keeps showing up in my photos, that
looks much bigger than a star, but I certainly don't see anything
that big when I look with my naked eye. It's to the left (east) of
Orion:
It's in the upper right of this photo, shot with a 20mm:

30 seconds of exposure so in one dimension it's maybe a minute of
rotation, or two, wide, but in the other, it's the equivalent of
several minutes long.
