Some more pics tonight with the refined PEC curve returning
consistent +/- 5 arc sec PE drift in RA.
Only problem was my index point has moved again! Grrr.
It was 3 o'clock on the index clockface and now is 4 o'clock.
Something that I can't fathom is shifting this and this time it's
not the worm grub screws.
Each set here was done right after a guide-save session in Bartels
scope drive and the curve smoothed.
Then dumped to the PEC.dat file...then finally used with NO GUIDING.
So it really is a custom PE for the section of the worm that has
already just been driven past...So technically it doesn't apply to
the section the capture is subsequently made on. If that makes sense.
In 3 sets , with 3 consistent PE figures under +/- 5 arc sec, this tells
me that the worm hob is fairly consistent around the circumference.
