Vixen Dew Cap Heating

Astrophotographers generally use two different focal lengths: Short focal lengths for overview photos and extensive deep-sky objects, and long focal lengths for objects which are further away. Our aspherical mirror optics offer the perfect solution for these scenarios. The VISAC primary mirror (Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and provides a fully flat and true-colour image over the entire image frame. Thanks to the three-element field corrector in front of the convex secondary mirror, there is no spherical aberration, coma or field curvature. Although the device is designed for astrophotography, it is also suitable for visual observations.

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

Note: Built-in infrared illumination not suitable for military purposes. This digital night vision device offers a particularly great viewing comfort thanks to its large display and observation with both eyes. Due to the digital design it is insensitive to over-radiation. The integrated infrared lighting makes it easy to observe in complete darkness. Due to the great insight you can also observe with some distance pleasant through the night vision device. The built-in rechargeable battery allows an observation time of about 8 hours. You can charge it via the included USB cable or an optional commercial power bank. The simultaneous observation and operation with the power bank is of course possible. Due to the 2x digital zoom you can look at their objects closer without approaching the object itself. The detection range is at night at about 120m - more distances, however, are possible in good low light conditions. You can observe this device very comfortably with both eyes. FEATURES Product for civilian use only Digital night vision device Digital zoom Integrated infrared lighting with 7 brightness levels Charging via power bank possible Battery operated: 5V 3000mA (energy for up to 8 hours) Range: approx. 120 m SCOPE OF DELIVERY Night vision device Padded shoulder strap USB charging cable Operation manual
