HeaterDream is a heating system for the optics of telescopes, eyepieces and photographic lenses designed to prevent dew (fogging) and frost on the optics during visual observations and photography. The main difference between HeaterDream and similar systems is the lack of the need to purchase a heating control controller. It is already built into every HeaterDream system. Those. having bought the system and having connected the power, we immediately get the working device without having to buy additional units. The use of modern technologies made it possible to make the controller compact, easy and to place it on the power wire. Control is made by only one button, each press of which is accompanied by sound signals.
How to use HeaterDream
The HeaterDream system requires a 12V DC power source. After the power is connected, a single sound signal will sound, which corresponds to the low power of the heater. To control the power of the heater in the controller, the PWM algorithm is applied, which saves a lot of battery power, which is extremely important in the field. The controller supports three levels of heater power – low, medium and high. Each press of a button is accompanied by one, two or three beeps. The number of audio signals strictly corresponds to the level of the selected power. One signal corresponds to a low power, two sound signals correspond to an average heating power and three sound signals correspond to a high heating power.
If dew has already appeared on your optics, then in this case you should set the maximum heating power and wait 20-30 minutes until the droplets of moisture disappear from the optical surface of your telescope. In the case of eyepieces, the time is somewhat shorter, and as a rule does not exceed 5-10 minutes. Then, it is necessary to reduce the power, selecting the value at which no further fogging will occur.
HeaterDream heaters should be tightly wrapped around the eyepieces or telescope lens and secured with Velcro. In the case of heating telescopes, it is best to wrap the heating pads around the pipe closer to the lens or corrector.
