Walking on the Moon

East Heavy Improvement

Recommended Posts

Last night, as an experiment,  I thought I'd adjust the RA balance on my mount to be slightly east heavy. 

Pleasantly surprised to get pretty consistent results beneath 0.75RMS - which for my mount is a 20% to 30% improvement . Obviously it's just one session and there are many other factors but if you haven't tried it yet it may be worth a go.

This is why friction drive is so good. The mighty Mesu has no backlash.  :grin:

Newcomers reading this might not know that the Dec equivalent of east-heavy loading is running slightly out of polar alignment and guiding only in the direction needed to correct for this. Again, the disabled direction has to become the active one after a flip.

Not sure SWMBO would approve.🙁

The trick is to be impossible to live with on account of  mount backlash problems. Done properly, this will see you given a Mesu next Christmas. It worked for me - twice.
