Kendrick Premier Heaters

Kendrick Premier Heaters are the best dew prevention strips for cameras and camera lenses, telescope optics of all kinds, binoculars and temperature sensitive electronics. Kendrick Premier Heaters work best in combination with a Dew Controller allowing the heat output to be regulated. The entire range of Kendrick Premier Heaters run on 12 VDC power.

The Premier Heater line is Kendrick’s flagship brand and their highest quality heater. They are built of the highest possible quality materials and to Kendrick’s electrical specifications. These are not off-the-shelf heaters! The best quality Velcro, elastic and flex heaters available are used in the Kendrick Premier Heaters. The cables are cold flexible down to temperatures of -40 and the cable housing is custom made for Kendrick to their specifications. Compare the performance of the Premier heaters to competitors who usually use cable that gets stiff and brittle in cold environments.

The Premier heaters are built to use only as much power as necessary and not waste energy. Foam insulation on one side minimizes heat loss to the air and directs warmth to the optics where it is needed.

Attaching Heaters

The heaters wrap around your telescope closest to the dew prone optic and are held in place by flexible elastic/Velcro attachments.

Eyepiece Heaters
Customers regularly ask if eyepiece heaters are necessary. They are just as necessary as the heater for the main lens or mirror in your telescope. In cool environments, the warmth of your eye causes the eyepiece glass to fog.

Kendrick manufacture four sizes of eyepiece heaters:

  • #2003 – for eyepieces on finderscopes.
  • #2005 – for 1.25″ eyepieces and also those without a huge body. (Plossls, Vixen Lanthanum and similarly sized eyepieces).
  • #2006 – for larger bodied (but not massive) 1.25″ and 2″ eyepieces. (Baader Hyperion, Orion Stratus and similarly sized eyepieces).
  • #2006-L – for very large body 1.25″ and 2″ eyepieces that require just a bit more heat. (Televue’s Naglers, Ethos and Delos, Celestron’s Lumina eyepieces, Explore Scientific’s eyepieces).

The DEW-Minator Large Eyepiece Heater!

This heater has been designed specifically for the ever increasing line of large format eyepieces available to the amateur astronomer. Plenty of power available for those cold or really humid nights yet can still be adjusted (via a Kendrick dew heater controller) for very mild, low power operation if your conditions call for it.

Like all Kendrick heaters, it has a sewn in, heavy duty elastic strap to allow you to securely fit it to any of your large bodied eyepieces.

How much power will my heaters draw

You can calculate the total current drawn when using more than one heater strip. This is helpful in choosing a controller suitable for your system. Remember the controller must be able to handle the amperage requirements of your heaters, no matter what controller setting you use. For example, if you set your controller to operate at 30%, the heaters will draw their full amperage 30% of the time. The other 70% of the time they will be off.

Coping with Dew Fact Sheet

Available in a range of sizes to suit optics from 1.25″ through to 16″ diameter Cassegrain telescopes. The new DEW-Minator is designed to fit large-format eyepieces, such as the Tele Vue Ethos series.

NOTE: Heater sizes refer to the diameter of the optic a heater will fit. For example, a 7/8″ heater fits telescopes with a 7/8″ diameter optic but is actually 28″(71cm) long. Choose from the following sizes:
