Brett,
it is either from a non concentric worm in the carriage or the
toothed belt pulley on the end being non concentric.
Either way, I'm happy it's cyclic and the only substantial PE.
Seems the worm
gear accuracy doesn't even come into it.
I have attached some shots of the jury rigged reduction which
is driving the worm at the moment.
Also attached are two old favourites from earlier tonight.
PEC was turned on for both shots but only sharpening applied to
the NGC5139 result. Seeing was only average, some high thin cloud.
