Dec adjustments are with a rather dodgy rotate by hand control, so I sit next to the mount with that within easy reach, with the accurate polar alingment Ive sometimes been able to go for 10 minutes without needing to touch it. After each sub I will move the guide star a few pixels in a random direction then start the next sub, dithering. No doubt the OAG setup I have would work very well on a good autoguided mount
