Vixen Dew Cap Heating

The 360 IV Lens Heater is designed to prevent camera lenses and telescopes from fogging up due to dew. It is also well suited for eyepieces.The heating element is a carbon fiber heater with a high thermal efficiency. The textile heating element provides great flexibility compared to other heating materials. The power cord (USB cable) has a particularly high flexibility to be still elastic at low temperatures. A very flexible Velcro tape allows for quick and easy attachment to and removal from the lens. The tape can be easily removed from the lens without pulling tightly. The heating tape has a very low power consumption and can be operated with a 10,000 mA battery for up to 14 hours.The Vixen Lens Heater 360 IV in detailWhen moisture in the air comes into contact with an object whose temperature is lower than the ambient temperature, small drops of water form - so-called dew condensation. Astrophotography often suffers from such lens fogging and the photo turns milky. Because the temperature and humidity change during the night and the camera becomes cooler than the ambient temperature, it is important to warm the objective's or telescope's lens by using heaters to prevent it from fogging. We recommend using the Lens Heater 360 IV when you want to do astrophotography or night photography on the coast, in the mountains or in cold regions. The heating elements are made of carbon fibers with improved heating performance, introduced for the fourth generation Vixen Lens Heater 360 IV. They efficiently keep the lens warm and fog-free with minimal power consumption. The heater temperature reaches 10 degrees Celsius above the ambient temperature (at 20 °C outside temperature and no wind). However, it varies according to influences in the environment. For power supply the lens heater is equipped with a detachable coiled cable (USB Type-C), up to 50 cm long. The 360 IV lens heater consumes only 2.5 W of power (5 V - 0.5 A). With a portable USB battery of e.g. 10,000 mA, it can operate continuously for about 14 hours (at 20 °C outdoor temperature). However, the operating time varies greatly depending on the environment and temperature. The soft and non-slip surface of the heating tape allows for easy attachment to the objective, eyepiece or telescope. The heater consists of a 30 mm wide and 600 mm long heating tape and is suitable for diameters up to 100 mm.FEATURESHeating type: carbon fiber textile heatingTemperature: 10 degrees Celsius above ambient outdoor temperature (at 20° C, no wind)Power source, power consumption: USB, 5 V, 0.5 A, 2.5 WPower cable: USB A (male)Connector: USB type C connector detachable coiled cable 20 to 50 cmOperating time: approximately 14 hours with fully charged 10,000 mAh battery (at 20 °C outdoor temperature)Recommended for lenses with a width of 30 mm and an outer diameter of 45 to 100 mmDimensions: 30 x 600 mmTotal weight: 67 gSCOPE OF DELIVERYLens Heater 360 IVUSB spiral cable

The A80Mf refractor is an ideal entry-level model for beginner astronomers who value high-quality optics. Thanks to Vixen’s quality controls, the 80 mm lenses are produced to an outstanding quality. The refractor comes with two Plössl eyepieces (6.3 mm and 20 mm) and a 90° star diagonal. The A80Mf is ideal for exploring the moon and the brighter planets. On moonless nights you can observe the Andromeda Galaxy or Orion’s Nebula. The 6x24 viewfinder makes locating celestial objects quick and easy.
