Hi Bill,
Thanks for your quick response.
I'm still trying to get a better polar alignment but I think I'm pretty close.
At the moment, I am just using the Tak 90 (500mm) with a Neximager to see if I can guide the mount. The LX55 doesn't have PEC but you can adjust the Az/RA and Alt/Dec backlash in % terms - must be the same for the LXD75. 100% according to the manual means it responds immediately while lower values makes it take longer to respond. The settings are in the Setup Menu of Autostar under Telescope. The scope is set at 3% which is how it came - maybe this is too low. I wonder what values these are on your mount?
I've seen the hypertune suggestions on lxd55.com but it looks beyond my abilities.
I will try your other suggestions over the next couple of nights and see if I can get on top of it.
Thanks again for your help.
Craig
