Kendrick Finder Heaters

Our Heaters require the purchase of one of our Dew Controllers in order to be functional. The heaters are not a stand-alone product.

All systems are all designed to run with 12 VDC with the exception of our #2021-A Digi_Klear Pad Heater which runs on 120 VAC.

 

Green Laser Finder and Pointer Heater Heater

Our Green Laser Heaters will keep your laser pointer and finder operational in cold temperatures. It has plenty of warmth to get the job done yet does not draw a lot of battery power (.1 amps when operated from a controller at a 50% setting). It has sewn in elastic attachments that slide over the pointer and keep it snugly in place.

If you have a different type of laser than the one shown here, contact us and let us know. We have the in house capability to make these heaters for many sizes and types of lasers.

Red Dot Finder Heater

S&T Hot Product 2010
Sky & Telescope Magazine has chosen our RDF Heater as one of the
Hot New Products for 2010!

SALE! 40% OFF!
The custom molded Kendrick RDF Heater presses onto a Red Dot Finder of the type shown in the photographs below and is held in place by friction. It includes a 1.8 meter (6') power cable. This heater will work with all of our controllers but if used with our MICRO controller, it will require the #2001-FL-ADAP Micro to RCA adapter.

Field testing has proven this heater to be very effective at dew removal and dew prevention. Typically a low to medium coontroller setting will be fine to keep this finder free of moisture. It draws very little current and at a typical 40% controller setting for example, this heater will draw only .08 amp (less than a 10th of an amp!)

Optical Finder Heaters

Optical Finder Heaters We have Premier, FireFly and MICRO FireLite heaters for these finders. They are wrapped around the optical components of these finders at either end. We highly recommend a heater at the eyepiece end of these finders as once the finder cools down, the moisture from your eye will immediately condense on the glass, making your finder unusable.

How To Use The System

We recommend that you put your heaters in place at the beginning of an observing session and turn your controller on right away. If you are using Premier Heaters, or heaters for Newtonian or RC Telescopes, we recommend a controller setting that represents about 20 to 40% If you are using FireFly or MICRO FireLite Heaters, we recommend a setting of about 60 to 80%.

If moisture has already condensed on your optics, we recommend covering the optics, turning the heaters on high and waiting 20 to 30 minutes. Once the moisture has cleared, lower your controller setting and resume observing.

 

Power Requirements

Power Supplies Our dew control systems require 12 volts DC. If you are using a battery to run the system, we recommend a 5 amp hour battery as a minimum. If you want to run the system from a wall plug, you will need a step down converter with a minimum output of 5 amps.

Pictured to the right are our Regulated 120 volt to 12 volt DC power supplies which are excellent for operating our systems from a wall socket. We also build portable 12 volt power packs and offer other power solutions that can be used with all your astro equipment that is used in the field. See Power Packs for more information on the power systems we offer.
