Do you have autoguiding capability with your EQ5 mount Trevor?
If not is it driven in RA?
If polar aligned, a driven EQ5 will give you 30-60sec unguided exposure time. Probably closer to 30secs unless you're anal about the polar alignment!!
That will necessitate the need for multiple exposures.
If you have a Pentax remote shutter switch this is easy.
Set the camera to multiple exposure mode and the maximum exposure setting: 30secs. Put your remote switch into the hold mode - this will make the camera take one shot, do a dark then take another shot etc etc as long as the remote button is depressed.
