Used Meade Field De-Rotator for 8/10/12" LX-200. No manual. I got this unit in a trade but have never tried to hook it up. Appears to be in excellent condition. New units sell for about $450. Will sell this one for $275, UPS shipping included to CONUS addresses. Payment by cashier's check, money order, or PayPal (credit cards ok, no surcharge).
