For many years, Astro-Physics has carried the Kendrick Dew Removal System. Jim Kendrick innovated the concept of dew removal systems in the mid-1990's to meet a persistent need in the burgeoning astronomical community for effective dew removal and prevention. His system quickly became the benchmark for dew prevention.
We are pleased to say that we believe the Kendrick Premier Dew Removal System to be the most appropriate setup for a large portion of our customers.The Kendrick Dew Remover System was developed to meet the need in the astronomical community for an effective dew removal and prevention system. This system has heaters for almost all the optical components used in amateur astronomy. Repeated field testing on many types of optical systems under many conditions and hundreds of satisfied customers has proven the effectiveness of this product over and over. It also has these other attractive features:
We are pleased to introduce a few additional products to our line-up.
Dew Controllers
Kendrick Premier Controller (KDRPC)
Note: The Kendrick Premier Controller will be available in the fall. Astro-Physics is pleased to offer the Kendrick Premier Power Controller Package. This is the most advanced controller of its type. The controller shown in the images here is called the "Observatory" version. Unlike the standard version, it has no display. There are two versions of it (both remotely controllable). One has a touch screen and another (known as the Observatory version) without any screen at all, designed strictly for remote control. A remote control web app is also underdevelopment and is looking very nice! Both version (Observatory and Display) can be operated remotely, using either:

Kendrick DigiFire 12 Controller (KDRDF12)
Also new to the controller line-up is the
Kendrick DigiFire 12. This mid-range power controller is perfect for those
astronomers who don’t require the full functionality of the Premier
Controller but still want enhanced digital control of their dew removal
system.

Kendrick Micro-D Controller (KDRMD)
The Micro Controller is designed for Astronomers and Astrophotographers who want the best in lightweight, compact, Grab'n'Go gear. Despite its small size, this controller is not small in its performance or build quality. It is well built and well thought out. The controller has two slotted tabs that can be used to attach the supplied lanyard so that the controller may be hung from a convenient location. Velcro tabs are also provided if you prefer to "stick" the controller to your telescope or mount. Also, the mounting tabs are convenient for anyone who wants to mechanically mount the controller with screws to a Dobsonian telescope base, Dobsonian upper tube assembly, inside an eyepiece box or wherever else one may wish to mount the controller. |

Premier Heaters | |
These heaters have been built to use only as
much power as necessary and thereby not waste energy. They have sponge insulation
on one side to prevent heat being dispersed into the atmosphere. The heat
is directed into the optics instead. As a result, less energy is needed
to keep your optics moisture-free. The heaters wrap around your objectives, label-side out, and are held in place by elastic/Velcro attachments. The Telrad heaters are held in place with an elastic band. The heaters for secondary mirrors are placed on the backside of the secondary and can be held in place by using the polyester batting found inside the secondary mirror holder. The .965/1.25" 1.25/2" and 2" units are considered eyepiece heaters. The 1.25/2" and 2" are also heaters for camera lenses and certain binoculars. New in the Premier heater line is the bino-viewer heater. This is comprised of two heaters connecting to one cable, using only one output. These handy heaters come in two sizes: up to 1.5" and 1.5" and over. We currently stock only the bino-heater for 1.5" and larger optics. |
Please bear in mind that the following table of amp hour ratings is to be considered accurate only if the controller is set at high. Under normal operating, conditions these ratings can be reduced by 40% to 60% as the normal controller setting is medium to low. This table will also help you determine which heater is right for your scope.

Due
to the cyclical nature of the duty cycle, it is best to power your dew removal
controller from its own power supply to avoid the resetting of your mount
and keypad. We recommend a deep-cycle, 12 amp hour rechargeable battery
for this system at minimum. If you are using household current, it must
be transformed to 12vDC with the transformer appropriately rated for your
amp requirements. Astro-Physics offers an AC power converter if you wish to use your your household current. Please review the information regarding the 13.8 Volt, 5-Amp Regulated Power Supply with Cigaretter Lighter Receptacle (PS138V5A). |
