Posted by Lenord on January 22, 2005, 11:06 pm, in reply to "derotator" I know of no Field de-rotator that works from the eyepiece tube. The only ones I know of rotate the whole focuser. It is an interesting idea however. Take Care --Previous Message--

Jay,
The field de-rotator is on a separate circuit from the Azimuth axis and turns at a different rate typically. It does chage rotation rate based on position of the optics IIRC.
Should you find a mechanical solution for your idea, the motor powered by the current PCB to turn it can likely be adapted to the mechanicals.

: focuser upon the derotator, ala Chuck Shaw.
: Does the derotator turn at the same rate
: as the azimuth axis?
