Tom Osypowski dual-axis equatorial platform for 15” to 18” DOB. Latitude 37 degrees plus or minus 3 degrees. Dual-axis drive makes it suitable for long exposure prime photography. Set up to take input from CCD auto-guider. New price is $2225 I’m asking $1800 or equivalent trade value. I’m willing to trade for equivalent value GEM or 7” to 10” Catadioptric scope on a decent mount.
