94051 Dew Heater Ring - 8" by Celestron

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 to your 8" Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the plastic retaining ring on your Schmidt 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 12V DC power source for consistent, continuous heat that will prevent dew from forming even under 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.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring's power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers' heater output ports, or to a third-party controller's heater output port. (Note: the ring's integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

• Heater ring provides the most efficient heating directly to the corrector lens to prevent the formation of dew
• Permanently mounts to your existing telescope tube for a seamless look–plus, you'll never forget to bring it with you
• Integrated thermistor continuously monitors the temperature of the corrector lens when used with the Celestron Smart DewHeater Controllers.
• Rigid, lightweight, and durable aluminum construction
• Included storage clip and cable management clip keep your cables organized

90205-22 Traceable® Water-Resistant Remote Probe Thermometer with Calibration; ±1°C accuracy (-20 to 100°C) by Digi-Sense

Water-resistant remote probe thermometer is perfect for wet areas-case is IP61 rated and shockproof, and probe is impervious to acid and solvents. Probe with 10-ft (3-m) flexible cord makes it easy to take temperature measurements in hard to reach areas. Supplied with suction cups, magnet, and Velcro® tabs to attach to any surface.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.

NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.

• Get accurate, reliable measurements with included NIST-traceable calibration
• Display updates every second
• Features MIN, MAX, and selectable °F/°C

Includes

Probe, cable, suction cups, magnetic strip, Velcro® strips, battery, and NIST-traceable calibration certificate with data.
