On a recommendation, I tried Mr Sheen for two months, but still "stiction" ruled. Did lols of reading of threads here and internet - conclusion - new teflon including central washer and "bumpy" laminate would be the best solution. So I did the EbonyStar addition to Az and Alt, put in new teflon washers - no lubricant of any type - it's superb.
Example - last night had a complete newbie on the scope - never moved a dob in her life - in no time she was tracking Jupiter at 266 magnification, no worries!
I've had to put the friction springs back on the Altitude motion - just too free otherwise.
However, it is only an 8" dob - not as heavy on the Az bearing as bigger ones.
Look for the threads - moderate handyperson skills and a few power tools will get the job done. And about $100 in parts.
Happy to answer questions. Eric
