For sale Kendrick 11" dew heater for Celestron C11, designed for 12.5" to 13.5" OD (310mm to 340mm), but fits just fine on a 10" SCT, too. Reason for sale -- sold my C-11. NOTE - this is the heater strip only, not the controller (see the pic, it's one of the long ones on the left <g>)! Excellent condition. New price is $63, will sell for $40 plus shipping OBO.
