The ASTRO R-LITE red light flashlight is the ideal companion at night to read star charts or make adjustments to the equipment without losing the dark adaptation of the eyes. The ASTRO R-LITE offers 3 functions: Continuous light bright / Continuous light dark / Flashing. The large diffusing lens results in a very large and evenly illuminated light cone, which can also be adjusted by a sliding mechanism. By using a power-saving LED lamp, the battery life (1 x AA-LR6) is up to 100 hours. Of course, the robust lamp housing made of aluminium is splash-proof according to IPX4 and therefore particularly well suited for outdoor applications. The side cutouts on the front of the ASTRO R-LITE provide a 360° signal function. The 50 cm long carrying strap with quick coupling and an extra belt clip included in the scope of delivery ensure that the flashlight is always quickly at hand. The ASTRO R-LITE should not be missing in any equipment. FEATURES ASTRO R-LITE Red Light Flashlight Reading star maps at night Dark adaptation of the eyes is retained Continuous light bright / Continuous light dark / Flashing 360° signal function Large diffusing lens produces a uniformly illuminated light cone Carrying strap and belt clip included Battery life up to 100 hours - Battery (1 x AA-LR6) Splash-proof according to IPX4Robust lamp housing made of aluminiumSCOPE OF DELIVERYASTRO R-LITE Red Light Flashlight Carrying strap Belt clip Battery (1 x AA-LR6)

With the 3-piece lens cleaning set you not only clean camera or binocular lenses, but also spectacles glasses and displays and screens of smartphones, laptops, tablets, etc. thoroughly and safely. When cleaning high quality optical lenses, you have to be very careful. After all, it would be very annoying to successfully remove the dust but leave a scratch behind. With the lens cleaning pen you can safely clean optical and coated glass. With the brush on one side you can remove coarser dirt before polishing the lenses with the other side. Just blow away fluff with the bellows. FEATURES complete set for safe cleaning of camera lenses bellows for removing coarse dirt particles and fluff without scratching the lens lint-free microfibre cloth approx. 14,5x14,5cm lens cleaning pencil for safe cleaning of optical and coated glass SCOPE OF DELIVERY 1x bellows 1x lens cleaning pen 1x microfiber cloth

Each dew shield threads into the front lens cell and effectively inhibits the formation of dew on the lens surface in humid/cool observation conditions. Reduces reflections caused by scattered light incident from the side. Protects the front lens from accidental contact and scratches. FEATURES Prevents fogging of the front lens Reduces reflections caused by stray light Protects the front lens of the telescope Use in humid/cool conditions Suitable for BRESSER MCX127/MC127 telescopes Easy to screw into the telescopic tube Length: 120mm , weight: 160g SCOPE OF DELIVERY Dew cap, 1 piece

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 perfect LED head torch for nighttime observations! Adjusting your eyes to the dark surroundings is very important when making astronomical observations. In dark areas, it is very difficult to use astronomical equipment without a suitable light. With normal lights, however, the light intensity is more important than protecting your eyes against bright light. Using these lights at night makes your pupils contract, which can make it difficult for your eyes to readjust to the darkness. The SG-L01, our first astronomy LED lamp, featured a built-in red LED that provided a solution to this problem. However, the red light did not offer optimal visibility. On our new astronomy LED light, the SG-L02, the LED lights produce warm light to improve visibility. They also ensure that your eyes stay adapted to the dark. The LEDs do not emit light in the sensitive range of 555 nm. The brightness of the white light can be adjusted between 3 and 42 lumen, while the red light can be adjusted between 0.28 and 7.62 lumen. FEATURES Dimmable red light ensures that your eyes stay adapted to the dark Built-in rechargeable battery, charges via USB Waterproof design LED colour can be switched from red to white 0.28 to 7.62 lumen for red light 3 to 42 lumen for white light Dimensions: 41 mm x 33 mm x 30 mm Weight: 29 g DELIVERY CONTENT SG-L02 head torch Strap (size S) Strap (size L) Pocket clip Cable for charging the battery (USB-A plug to USB Micro-B plug)
