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 BT-120 SF Giant Binocular with 62° LER Eyepieces 20mm
Giant binocular for observing the starry sky, nature and landscape. Observe the beauty of the starry sky at night and distant objects in nature during the day. Globular star clusters, glowing gas nebulae, the moon with its craters and even planets can be observed wonderfully on a clear night. But also all other distant things in nature and landscape, even ships and airplanes can be seen in detail. With the all-round binoculars of the EXPLORE SCIENTIFIC BT series, you can get up very close. Thanks to the large, light-gathering lenses and the professional coatings on all lens surfaces, these binoculars produce bright and brilliant images even at night and at twilight, providing a special viewing pleasure. The comfortable 45 degree viewing angle allows fatigue-free use, even when the binoculars are tilted upwards towards the zenith.  A large binocular can also be called a double refractor telescope Binoculars such as these can really be described as a double telescope.  In this configuration, the full light gathering power of one single telescope is available to each eye. Experience a whole new dimension of observing as a consequence. Objects are reproduced almost vividly in these binoculars and observing with both eyes is a very relaxing experience. Last but not least, this comfortable way of observation increases the recognition of the finest details (particularly in fainter deep sky targets) and effectively prevents eye fatigue. Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen  The BT series binoculars are designed for tough outdoor use. The IPX6 sealed and nitrogen-filled design effectively prevents fogging of the internal optics even under difficult weather conditions. The very light magnesium housing saves weight and makes it easy to handle. Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included. EXPLORE SCIENTIFIC is an established manufacturer of extremely high-quality eyepieces in the astronomy scene. An optical system is only as good as its weakest component. Therefore we have decided to deliver these giant binoculars with a pair of quality eyepieces of the 62 degree LER series. With an apparent field of view of 62 degrees and a focal length of 20mm, the BT-120 binoculars produce a 33x magnification. Thus these wide angle eyepieces offer a very good overview (field of view 1.8 degrees) at moderate magnification. The large interpupillary distance of these LER (long eye relief) eyepieces of 15mm and soft silicone eyecups, which can be turned inside out, also guarantee a comfortable and relaxed view. For astronomy, a flat and sharp image field is advantageous and offers a particularly impressive viewing experience even during the day. Due to the waterproof design and the argon filling, these eyepieces are absolutely durable and easy to clean. Interchangeable eyepieces with 1.25 inch / 31.7mm plug-in diameter Adjust the magnification and field of view to your individual needs and choose from a wide range of available eyepieces. All eyepiece types with a plug-in diameter of 1.25 inch / 31.7mm can be used with the binoculars of the BT series. Especially recommended are EXPLORE SCIENTIFIC eyepieces of the 62 and 82 degree series with focal lengths from 8 to 26mm (see item No. 02188xx and 02196xx). The magnification can be varied from 25x to 75x (focal length binoculars : focal length eyepiece = magnification). The eyepieces are held in the binoculars by a precise brass compression ring clamp and guarantee a tilt free position.  Use of colour and nebula filters for astronomical observations Increase the contrast and visibility of objects and details by screwing the corresponding filters directly into the thread of the eyepiece sleeves. The use of colour and nebula filters must of course always be done in pairs. Suitable are all EXPLORE SCIENTIFIC screw filters with 1.25inch / 31.7mm diameter (see item No. 03102xx)  Comfortable 45 degree view and helical single focus The 45-degree viewing angle allows a relaxed observation position even when the binoculars are tilted strongly. Also the individual interpupillary distance can be adjusted in a range from 54 to 76mm. With the fine helical individual focusing, precise focusing is achieved effortlessly. Extendable dew caps The integrated dew caps can be removed in high humidity and cold conditions. This avoids fogging of the outer objective lenses and effectively shields additional control light coming in from the side. Integrated carrying handle A metal carrying handle located at the center of gravity facilitates transport and ensures a secure hold during tripod assembly. Suitable tripods and tripod connectionWhen using these large binoculars, a sturdy photo tripod with an appropriate load capacity is highly recommended. The connection is made via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) in the tripod adapter of the binoculars. The ideal solution is to use the optional available EXPLORE SCIENTIFIC U-Mount with field tripod (item No. 0114300). This is specially designed for the large binoculars of the BT series and carries these binoculars absolutely securely. The excellent support mechanism, with adjustable friction in both axes allows easy moving and tracking. The binocular position is kept stable depending on the adjusted friction intensity. Vibrations are reduced to a minimum by the massive construction of the U-Mount and the large stainless steel tripod. Even at high magnification there are no discernable vibrations and this allows the finest details to be observed in a chosen target.FEATURES Large binoculars for observing the starry sky, nature and landscape Observe globular star clusters, glowing gas nebulae, the moon with its craters and even planets Also wild animals, ships and airplanes can be seen in detail Highly light gathering lenses produce a bright and high-contrast image All-round binoculars, but especially suitable in twilight and at night The comfortable 45 degree viewing angle allows fatigue-free use One complete lens telescope with the full light gathering power is available per eye Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included 33x magnification and an apparent field of view of 62 degrees, true visible field of 1,8 degreesLarge interpupillary distance of 15mm to the eyepiece lens for comfortable viewing Eyepieces interchangeable and with standardized plug-in diameter of 1.25 inch / 31.7mm The magnification can be adjusted with optional eyepieces from 25x to 75x Precise brass eyepiece compression ring clamps for tilt-free fitColor and nebula filters can be used for astronomical observations Extendable dew caps prevent fogging of the outer objective lenses and stray light Integrated carrying handle facilitates transport and mounting on the tripod Tripod connection via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) Tripod recommendation: EXPLORE SCIENTIFIC U-mount with field tripod (Art.No. 0114300) Objective type: Air spaced achromatic lens (2 elements/ 1 group) Coating: full multilayer coating on all optical surfaces Aperture, focal length and aperture ratio: 120mm / 660mm / F=5.5 Sealed to IPX6 standard and nitrogen filled: yes / yes Close focus distance: 35 meters Eyepiece mount diameter: 1.25'' / 31.7mm Adjustable interpupillary distance: 54 to 76 mm Helical single focus: yes BAK-4 prism system for a bright and high-contrast imageDimensions and weight of binocular: 654 x 290 x 156mm, 8.3kg Housing colour of binocular:  white What's included Giant binocular with carrying handle (without tripod)Eyepieces ES 20mm 62 degrees LER Series (2pcs)Precisely fitting foam insert for transport Dust covers for objectives and eyepiece sockets Instruction manual

Vixen AXD2 with VMC 260 Maksutov-Cassegrain Telescope
AXD2 GoTo mount with VMC260L telescope set The AXD2 mount comes with the new STARBOOK TEN controller and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars. This telescope set has everything that you need for hobby astronomy. The set includes a telescope, a mount with automatic tracking and a stable tripod. Featuring the STARBOOK TEN controller, the telescope locates celestial objects automatically so that you don’t need to search for them manually. Even if you’re not an expert, you can still give your friends an exciting tour through the night sky! The AXD 2 mount in detail: Robust construction and lightweight housing with 30 kg load capacity (photographic) The RA and DEC axes are made using the A7075 superalloy, one the strongest aluminium alloys. The stability of the A7075 superalloy is stronger than titanium, which is known for its strength as a lightweight material. Its thickness is 38% less than titanium. Using the A7075 superalloy for the axes ensures that the AXD mount is both lightweight and stable. 21 bearings The rotating parts of the AXD mount have a total of 21 bearings. These ensure uniform motion in order to swivel the telescope and track objects. Stepper motors Vixen uses precise stepper motors for the mount in order to ensure optimal performance. The motors are controlled via a micro-step motion control system, which eliminates the disadvantage of stepper motors with large steps. The system generates 400 impulses per second at a high speed. This results in very quiet scanning with no vibrations. The stepper motors on the AXD mount have sufficient torques. This is most significant when working at high magnifications and photographing with a CCD camera with small pixel sizes. Worm gears The sizes of the worm gears were increased in the latest Atlux version. The AXD mount has 270 teeth in the RA axis and 216 teeth in the DC axis. Both axes are 50 mm in diameter. This ensures that the mount operates with precision and stability. Low backlash The Vixen micro-step motion control system ensures that the stepper motors run uniformly at low and high speeds. This eliminates the need for reduction gears in the motor and therefore reduces the backlash in the gears. Elegant design The flat sides of the mount were designed based on previous generations of the New Atlux range. The white and silver housing provides a modern and elegant exterior with high functionality. The AXD is the flagship model in the Vixen mount range. Original motor layout The solid RA and DEC motor units are arranged in the lower part of the mount. This means that they automatically act as a counterweight. As a result, you require far fewer weights on the counterweight bar. On small devices, no counterweight is required. The counterweight bar can be slid fully into the housing. Polar finder scope The AXD mount is equipped with a 6x20 polar finder as standard. The polar finder features an integrated scale, which provides a quick and easy way to polar align the telescope in the northern hemisphere. For observations in southern latitudes, the polar finder features an image of the Octans constellation, which can be aligned with the night sky. VPEC periodic error correction Periodic errors on mounts are usually measured and corrected by the user. Unlike the old StarBook controller, the STAR BOOK TEN controller saves these errors permanently. The periodic error of the mount is measured in the factory and corrected before delivery. This is known as VPEC and functions automatically as soon as you use the mount. It delivers an accuracy of +/- 2.8 arc seconds. You can increase the tracking accuracy further by saving your own recorded periodic errors. The VMC 260 in detail The optics of the VMC260L are significantly better than the traditional Schmidt-Cassegrain telescope. Despite its high 3000 mm focal length, it is just 650 mm long. Featuring a large 260 mm aperture, the telescope collects large amounts of light for serious professional observations and photography of the planets and countless deep-sky objects. Thanks to the dielectric mirrors, the VMV260L guarantees razor-sharp images and maximum brightness. The open lens barrels cool the telescope quicker than conventional closed Cassegrain systems. The telescope can be used with an optional 0.62x focal reducer to reduce the aperture ratio to 1:7.1. This shortens the exposure times and allows you to photograph large objects. The telescope comes with a standard dovetail bar and a carry handle that doubles up as a camera holder for night sky photography.
