Can someone offer some advice as to what I might do to correct this issue with the DEC rotation being “non-symmetrical”? My DEC has always given me issues with guiding. I thought issue was with backlash but info I have read from Astro-baby and a video from Martin’s Astrophotography show that not an issue based on initial testing.
while doing that test I noticed that during the rotation it is not quite as smooth all the way around. I don’t hear a rubbing but I can feel a small amount of friction/resistance. Does anyone know if the little inset grub screws on the DEC cylinder could possibly be used to realign the Mount so the rotation is symmetrical?
