Kendrick Finder Heaters
Heaters are attached to the sides of these finders as shown above and the heat is transfered laterally into the optic of the finder, keeping the dew and frost free.
The heater is 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.
We recommend that you put your heaters in place at the beginning of an observing session and turn your controller on right away.
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.
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.
