The sky sensor for sale is the first stand alone vixen goto drive.
1 star alignment
2x and 60x slew speed
RS232 port accepts simple ASCII commands.
The kit includes 2 motors , clutches and cables.
The motor housing can be easly mounted on SP mounts, but I drilled one hole in both of them to make them fit in the cg-5.
I tested the goto and traking , they are both very accurate.
Manual is included
175U$ plus shipping.
thanks for looking.
