They also tend to capture stray light, which reduces the contrast of the target.\u003c\/p\u003e\n\u003cp\u003eAs many astronomers and astrophotographers have experienced, on clear nights, dew is often a real problem and if it forms on your lens it can render your nights observing session over. After only a very short time, the optics can start fogging, making viewing or photography impossible. A good dew shield reduces the risk of fogging and extends the observing time. \u003cem\u003eNote\u003c\/em\u003e: on extremely humid nights, dew heaters will also be required.

Each channel controls two outputs of a total of four outputs. Each channel is able to maintain a duty cycle of 5% at low setting to 95% at high setting. The Astrozap dew regulator is designed to operate at 12 volts DC and should never be operated at any other voltage. The total current capacity for all four outputs is 5 amps - We recommend using Astrozap Heater bands however other brands can be used once they are a similar rating.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe controller is supplied with a cable about 1.8 meters long, which is equipped with a cigarette lighter plug. A 5-amp fuse is integrated in the connector. The red power LED indicates that the controller is being powered and the two red lights on the outputs indicate the power level of each channel. The brighter the red LEDs, the longer the duty cycle for this channel. When it is set to the lowest setting, it is effectively turned off. It also includes a 2-inch Velcro strap for attaching the controller to a suitable area of your telescope mount.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003cul\u003e\n\u003cli\u003eVoltage input: 12V DC\u003c\/li\u003e\n\u003cli\u003eVoltage output: 12V DC\u003c\/li\u003e\n\u003cli\u003eMaximum current: 5 A (fuse in the plug)\u003c\/li\u003e\n\u003cli\u003ePower range: 5% to 95%\u003c\/li\u003e\n\u003cli\u003eNumber of channels: 2\u003c\/li\u003e\n\u003cli\u003ePower port: Cigarette lighter plug\u003c\/li\u003e\n\u003cli\u003eLength of power cord: approx. 1.8 m\u003c\/li\u003e\n\u003cli\u003eHeater output ports: RCA sockets\u003c\/li\u003e\n\u003cli\u003eNumber of output ports: 4 (2 per channel)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Astrozap","offers":[{"title":"Default Title","offer_id":40705686732995,"sku":"AZ-720","price":289.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/AstrozapDewHeaterController4Port.jpg?v=1631879686"},{"product_id":"dew-heater-bands-various-sizes","title":"Dew Heater Bands - (Various Sizes)","description":"\u003cp\u003eIf the optics fog up, this normally means an early end to what could have been a successful astronomy session and there's nothing more frustrating for an Astronomer or Astrophotographer when this happens on rare crystal clear nights.
