as the title suggests, I've noticed that the RA axis of my HEQ5 pro mount has some give. I don't notice it while the clutch is unlocked, but it's very obvious with a locked RA clutch. Any suggestions on what could be causing it/what adjustments need to be made?
yesterday evening, I started observing the moon and sketching crater Copernicus even 15min before sunset.
