Warning notes
  • General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not expose the device to high temperatures.

Vixen SG-L02 Headlamp red-light white-light
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)

Explore Scientific ASTRO R-LITE red light Flashlight
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)
