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.

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)

BRESSER Messier AR127s/635 EXOS-2 PMC-Eight GoTo Telescope Set

A compelling combination: Enjoy spectacular sky observations with the BRESSER Messier AR-127S/635 tube and the EXOS-2 PMC-Eight GoTo mount, both day and night. Thanks to its compact design, the telescope is perfect for wide-field observations, such as breathtaking views of the Andromeda Galaxy or large gas nebulae. The four-lens achromat with its large 127 mm aperture provides high contrast and minimal color aberration. The high-quality solar filter also allows safe observations of our home star. This modern mount provides precise tracking and intuitive sky navigation via the app for all your astrophotography and exploration needs. The Telescope As a quality telescope for night and solar observations, the BRESSER Messier AR-127S/635 tube with its compact design offers particularly large and bright fields of view. Be sure to use it to observe the Andromeda Galaxy! The light from this object, visible over 2 million light-years away, is as spectacular through this telescope as observing large gas nebulae. Thanks to the large aperture, the Messier AR-127S/635 can use nebula filters that enhance gas nebulae with remarkable contrast. The special construction as a four-lens achromat achieves minimal color error and better photographic correction than comparable two-lens devices, even with a very fast focal ratio of f/5 for a refractor. With the high-quality solar filter, you can safely observe sunspots, eclipses, and planetary transits. (Warning: Never point the telescope at the sun without a solar filter.) The Mount The EXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo mount is equipped with a modern, highly accurate GoTo control system. It consists of a robust Wi-Fi controller unit providing all necessary interfaces. The NEMA-11 stepper motors are connected directly to this unit by cable, and an ST-4 compatible autoguider interface is also available. Additionally, the control supports micro-step mode for precise tracking. Intuitive operation via app and graphic star map The ExploreStars app, developed specifically for the PMC-Eight system, offers an intuitive, visually pleasing user interface. The app displays available alignment stars for system initialization and all celestial objects in the database as a star map with additional text information. All objects can be easily viewed and selected. Powerful controller unit with Open GoTo for customization The heart of the controller unit is a fully autonomous, 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP functionality. This setup enables remote operation via browser, ASCOM, app, or serial connection. Open GoTo allows custom firmware to be written and loaded onto the controller, enabling individual customization of device functions and the creation of custom object lists. Polar finder included The included pre-mounted polar finder scope enables quick and precise alignment and long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the usability of the polar finder.

BRESSER Messier MC-100/1400 EXOS-2 PMC-Eight GoTo Telescope Set

This set, consisting of the Messier MC-100/1400 telescope and modern EXOS-2 PMC-Eight GoTo mount, is perfect for the demanding beginner's entry into the fascinating world of astronomy! With the long 1,400 mm focal length and the 100 mm aperture, you’ll already be able to see breathtaking details of planets and smaller nebulae. The compact Maksutov-Cassegrain design makes the telescope particularly portable and easy to handle. The mount, equipped with practical GoTo control and the user-friendly ExploreStars App, makes celestial navigation easy. The tracking, which compensates for Earth's rotation, is also extremely precise. With the high-quality special filter, you can safely admire the Sun’s surface through the telescope. The Telescope The compact optics are a defining feature of the Messier MC-100. The long 1,400 mm focal length allows for relaxed planet observations at high magnifications. Thanks to its short tube length, the telescope is ideal for mobile use. The 100 mm aperture allows you to observe smaller planetary nebulae in the vastness of space. Spot the famous Ring Nebula in the constellation Lyra or admire the Dumbbell Nebula in the constellation Vulpecula. You can also explore the sky during the day: With the safe objective solar filter, you can safely observe sunspots, eclipses, and planetary transits on our home star.
