I have an Orion 12 volt Dew Zapper that fits onto an 8" SCT. It will also fit onto the Meade 7" Mak. Works great at keeping dew off the front corrector. I've sold my LX-200 and I don't need this anymore. $26 includes shipping in CONUS. Paypal OK (no fee), money order or personal check also OK (I'll have to wait for it to clear).
