The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts on your 14" Celestron Schmidt-Cassegrain (manufactured in 2006 or later), EdgeHD, or 36cm RASA optical tube, replacing your retaining ring so you'll never be caught without it. The installation process is quick and easy.

The Dew Heater Ring replaces the retaining ring on your corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation. Simply plug the ring into an external 12 VDC power source for consistent, continuous heat that will prevent dew from forming under even heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

Q: 9. it is unclear to me how this adapter attaches to the telescope eyepiece. Do I need anything in addition to this item?

A: The Celestron T-Ring for Nikon F-Mount Cameras changes the camera lens mount to a T-mount. This would then need an adapter on the Telescope side to change the telescope to a T-mount as well. Basically this adapter is half the picture, one needs an adapter on the telescope side as well, as most are not native T-mount.
