Thanks Barry.
I have to admit the word "orthogonality" has always sent shivers down my spine. I fear that there's a 50% chance I would make it better and a 50% chance I'd make it worse. I've never tried adjusting my LX200 in the 10 years I've had it.
I have found this on how to do it:

Could you recommend any other instructions on doing it? tips? know anyone in WA who's done it so can help?
Thanks,
Roger.
