For very short bursts, yes. 10 secs or so will keep the planet in the frame but does make it harder to process for the software. If you are using an EQ mount or tracking with a DOB and the target stays reasonably central then more frames are possible and better. You don't need to guide as you do with longer exposures for DSO targets though.
