Length of exposure before rotation is an issue?

[Poita (Peter)]

For imaging the planets, mars, Jupiter, Saturn, how long an exposure can you take before their rotation becomes a problem?

There is a useful table right here on Ice in Space in the excellent piece written by Mike Salway under the article RGB planetary imaging with a monochrome camera in the projects/articles-astrophotography section.
See the left hand site menu.
