Eden, not to diminish in anyway your good advice to Jakob, I need to comment on your advice ..... "You might wish to increase the delay between guiding camera exposure times so that your mount is making fewer corrections. Depending on the brightness of your guide star, 3-4 seconds is a good value."
This may work for cameras such as the SSAG or SBIG ST-1 but this will not work for the ZWO ASI cameras, or potentially any other video streaming type camera.

What you're saying here glend is correct and thanks for pointing that out.
The recommendation I made above doesn't apply to all cameras/scenarios. Factors which should be taken into consideration when determining preferred exposure time for the guiding camera include the sort of camera you're using, whether you're using an OAG/AO or externally mounted guide scope, your focal length, the brightness of the target guide star, accuracy of your polar alignment and a few others besides.
