Just in case it helps. I use a Starlight Lodestar on a £50 second hand 114mm f5 reflector as the guider. I found I can frequently use a 0.5s exposure and get good tracking. Tts guiding an f4.4 250mm aperture Newtonian mounted on an EQ6 Pro. Occasionally I have to turn up the RA agressiveness, but not always.The Lodestar is a winner. Tempted to upgrade to a Superstar for those occasions where stars are few and far between.
