Dew Heater Controller is an essential device for any astronomer. Often the telescopes go through a widespread problem. That is dew. Moreover, these dew drops can damage the properties of the device. Also, in the absence of proper precautions, you may miss a lovely opportunity. However, amateur astronomers often make a mistake. They do not give much importance to a dew control system. Hence, they tend to lose to observe any beautiful phenomenon of the night sky. In this article, you will learn about the dew heater controller. This is a piece of beneficial equipment to protect a telescope.
The Dew Heater Controller
This type of Heater is the most effective solution to control dews over the glasses. Moreover, it is a do-it-yourself model. Also, the machine consists of two parts. They are Controller and the Heat Strip. Furthermore, the usage of the device is not at all complex. You have to wrap the strap around the telescope over the point of the dew.
Furthermore, you will find that all parts of the strip get evenly distributed heat. Moreover, the elastic attachments help the heat strip to stay in position. Besides this, there is also an RCA output jack. It helps the device to connect to the controller.
Moreover, you can easily fabricate the strip with a Nichrome wire loop. This wire consists of an alloy of iron, nickel, and chromium. Also, these materials make it really strong and flexible. Moreover, you need to take a tape of appropriate length and wire to make the strip. Also, connect the device with the RCA plug to the loop by using proper wires. Finally, you should wrap the whole thing carefully. However, you should attach the adhesive tape to complete the Heater strip.
Some Other Features On Monocular
You should always remember that the wire loop has appropriate resistance power. Moreover, it can draw a specific amount of current from the source. However, before implementation, you should have a test-check. Also, in case of inadequate heat, you have to combine multiple loops. These loops can act as a single heating element.
The Dew Heater Controller works similarly to a PWM Controller. Moreover, it allows you to adjust the level of heat as per specific requirements. Also, you can feed power to multiple heater strips. Furthermore, it is better to supply power to the controller through the DC input jack. You should also ensure the different specifications of the whole device. Moreover, the 47K Potentiometer can control the operations of the PWM Controller. In turn, it can also control the temperature of the heater strip.
An astronomer should test the prototype first before final implementation. Also, the average length of the Nichrome wire should be around 38 cm. So, you should have everything ready to start the experiment immediately. However, there is no feedback mechanism for this controller. Hence, you should take extra care and protection while using it. Moreover, you should ensure not to over-heat the delicate lenses of the telescope.
