As per my video link above I have just noticed a vibration and noise issue from the RA axis. It only does it when going from the west side to the east side of the mount. Also, the Go-To speed must be at 1000 or 1800. Whats up???

thanks  tony

BTW - here is the description on my YouTube page for this video:

Tonight, May 22 - 2021 I noticed a vibration from my Astro-Physics Mach2 mount at the 1000 and 1800 Go-To rates coming from the RA axis. It only occurs when going from the west side of the mount to the east side.

Clip 4 is @ 600 WEST SIDE to park 3
