Re: ATM gears and such

Hi Peter,

I have no numbers for you.  When star drift aligned, the mount will track
for hours without needing attention.

What method would you recommend to record the periodic error.... I'd guess
by misalligning the mount from the pole and let the stars zigzag across the
film and measure the zig or zag as the case may be.
