Not really, if you point your bow or rear in front of the target, and point the periscope/UZO at 0 or 180 degrees you can also do it moving. It then completely cancels out your movements. But you're limited in your directions ofcourse. It usually takes just a moment (wel under a minute) so you can back to your original course quickly.
