I fitted my mount with the Rowan engineering belt drive kit, last night was the first chance to try it out so this is an additional 80 mins with new drives added to 90 mins with the old gears. The mount is now as quiet as a mouse and the guide graph much tighter, the only changes required were a lowering of RA aggression and a tweek of hysteresis in phd. There is obviously a difference in the processing of the 2 images, they were done on seperate nights and the moon was much brighter last night so not the fairest of comparisons.
Original 90 mins

80 mins with drive belts, almost full moon.

Combined images, deleted the horrible version. That'll learn me to do things after3 hours sleep.
