Thank you Greg, Carl, J,

Nettie the Omega Cent set was blown out by cloud just after
we chatted...this set was started after midnight.

Fred, Mike, : 20sec subs x 65 frames whatever that turns out to be
in total exposure time.
PE curve is generated by the align file in Nebulosity (as long as I
do no manual guiding adjustments).
As this represents about 4 turns of the worm it is a workable PE
measurment.
This set was done from teeth 65 to 70 on the worm gear.
PE was measured at +/- 6 arc sec at 1.14 arc sec per pixel.

Steve
