Re: Spikes in DEC #Guiding

This indicates a severe unbalance in Dec which puts a lot of pressure on the gear teeth and causes high friction.
Check your Dec balance by sending the mount to Park1 or 4 or 5 and loosening all 4 clutch knobs fully. You must be well balanced in Dec, especially if your load is heavy. With clutches loose, feel the weight as you move the scope back and forth.

I seem to have some very consistant spikes (about 3" in
magnitude) every 130 seconds now. I have monitored for about 20 minutes long and they are very predictable... Note that I have reduced exposure time to 2.0s, just to see if I would see more spikes when sampling faster.
