HEQ5 Pro SynScan Periodic Error Analysis

This is my first analysis of the Periodic Error after I stripped down and cleaned up the mount some months ago.

Not bad at all!

I am absolutely satisfied with the result thanks also to the good worm adjustment I was able to achieve, after many hit and miss.
