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.
Featuring an improved design and optical properties, this compact field corrected Maksutov-Cassegrain system is Vixen's answer to Schmidt Cassegrain and more conventional Maksutov Telescopes. Instead of a heavy corrector plate, the Meniscus corrector is located directly in front of the secondary mirror. As a result, the Field-Maksutov does not dew up easily, as most conventional SCT s and Maksutovs do, when exposed to humid air. Thanks to the VMC's open tube system, the optics cool down quickly, ensuring that the telescope is ready for use in no time - again offering advantages over traditional Schmidts and Maksutovs, which can take a long time to acclimatise and reach thermal equilibrium. The long focal length of the VMC allows you to make detailed observations of planets, distant galaxies, individual lunar craters and mountains and many other celestial objects. The mirror is manufactured using an advanced coating deposition technique, normally reserved for research-grade instruments - ensuring an extremely smooth and precisely-finished optical surface. This, combined with the secondary corrector delivers extremely pleasing visual and photographic performance, with a very flat field. Unlike the primary mirrors in many rival SCTs and Maksutovs, the VMC200L's primary is fixed and doesn't travel on a focuser baffle, adding to stability and as a result this telescope does not suffer from "mirror flop" or focus shift.The focuser is a conventional, smooth-running single speed rack and pinion design, which ensures stability, even at high loading. It can be simply upgraded to dual speed use for finer focus control with the X000143 Vixen Dual-Speed-Focuser, if required.The telescope is supplied with a standard Vixen profile mounting dovetail bar and is also supplied with a carry handle, which makes transport and mounting much easier. The carry handle can also double up as a mounting platform for other accessories, if required.The VMC200L is also supplied with Vixen's superb 7x50mm illuminated finderscope, with variable brightness control, to help you guide the telescope accurately to targets.Last, but not least, is the inclusion of Vixen's extremely useful flip mirror system, which allows for mutual mounting of 1.25" eyepieces or accessories. Both eyepiece holders can be unscrewed, revealing a standard T2 mounting thread, which allows easy mounting of many cameras or other photographic accessories to either port. The ability to be able to flip simply between visual use and a camera is of great help when trying to centre and image compact targets - speeding up acquisition of targets and making better use of your time under the night sky.FEATURES

The optics of the VMC260L surpass the traditional Schmidt-Cassegrain and this tube is only 650 mm in length, despite its long focal length of 3000 mm . With its large aperture of 260 mm , the telescope collects light for serious professional observations and photography of the planets, as well as countless deep-sky objects. The dielectrically coated mirrors of the VMV260L guarantee high sharpness and maximum brightness. Thanks to the open tube, this instrument cools down faster than conventional closed Cassegrain systems, and (having no front corrector plate) is not as prone to dewing issues either.An optional 0.62x focal reducer is available for expansion to reduce the focal ratio to 1: 7.1. This results in a shortening of the exposure times and the increasing the field of view, thus increasing the ability to photograph larger objects in the sky.

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 Vixen SD103SII Telescope OTA is a new 103 mm apochromatic refractor with high-performance Super-ED glass (= SD). The advantage of this SD refractor is its short length and low weight. The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material reduces chromatic aberration across all colours.The new Vixen SD103SII no longer uses spacer plates, which leads to a significantly better image quality, especially with bright stars. In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates. In addition, you will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp as well as with extremely high contrast. Also look at the ring planet Saturn or the cloud bands on Jupiter. But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed in impressive detail.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors allow illumination with a 44 mm image circle for full format SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60 mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included folding mirror allows comfortable observation even in unfavourable observation situations and additionally offers a T2 thread for connecting a DSLR camera. This allows you to observe in straight line or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure grip when transporting the telescope. FEATURESObjective lens: D=103 mm, multi-coated 2-lens SD apochromat without spacer plates No more spikes on the stars Focal length: 795 mm (f7.7) Resolution and limiting magnitude: 1.13 arcseconds; 11.8 Light gathering power: approx. 217x more than the human eye Dimensions and weight: 115 mm dia x 810 mm; 5.5 kg Viewfinder telescope: 7x50 illuminated Adapters and connections: 60 mm thread, 50.8 mm and 31.7 mm socket, thread for T-ring Connection: 50.8 mm and 31.7 mm socket with flip mirror / folding mirror Photography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor SD103SII Telescope (OTA) Tube clamp with dovetail Dew cap Flip mirror / folding mirror Carrying handle Dovetail rail 7x50 viewfinder
SXD2WL SD115SII Complete Telescope Set with GoTo Mount, Tripod and EyepiecesThis high-quality apochromatic refractor telescope-set impresses with its 115-mm-SD optics. The telescope is made in Japan and scores with its excellent workmanship, sharpness, and contrast performance. The advantage of this
SD refractor lies in its light
weight and very color-true and high-contrast imaging. You will be amazed when you use it
to observe the moon surface with its craters or Saturn with its
ring system. On Jupiter, on a good night, you can also see the two bright cloud bands and many smaller details as well as the great red spot on the planet. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting objects. Even weaker celestial objects become visible with this large aperture of 115 mm under a good sky.This telescope set "Made in Japan" leaves nothing to be desired. The FPL53 glass used in the telescope reproduces an extremely clear and sharp image
due to exceptionally high elimination of residual color errors. The
SD glass is designed to bring all rays – violet, red,
blue, yellow, and green – very precisely to the same level. The
special lens material thus reduces chromatic aberration across all colors. In the new Vixen SD115SII, no spacer plates are used anymore, which leads to a significantly better image quality especially with bright stars. Consequently, no spikes are seen on the stars in photographic images, which would otherwise be caused by the spacer plates.In combination with the optional SD Reducer HD Kit or SD Flattener HD (not included), this refractor telescope enables illumination with a 44-mm image circle for full-frame SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally developed for
visual observers and photographers with APS-C cameras.
However, the new SD series is also optimized for use with full-frame cameras due to the use of new internal diaphragms. The large 60-mm eyepiece holder also allows the attachment of heavy cameras without tilting. Furthermore, the supplied flip mirror
allows comfortable observing even in unfavorable viewing conditions and
also provides a T2 thread for attaching a DSLR camera. So
you can observe at an 90° angle or directly. The carry handle attached to the tube clamps provides safe handling during transport of the telescope. The sturdy metal tripod allows vibration-free mounting of the telescope and mount even in windy conditions. The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet . For user-friendly control of the mount, the free app STAR BOOK Wireless is available. This allows you to use practical celestial navigation functions like the automatic GoTo swiveling to specific celestial objects simply via your smartphone or tablet. Since the power consumption of the traditional LCD screen (STAR BOOK TEN) is eliminated, the power consumption of the mount is reduced by up to 20%. This enables astronomical observations and astrophotography over longer periods.
When you tap the desired celestial object from a list, it is automatically swiveled into the telescope's field of view and tracking begins. An existing STAR BOOK TEN control can also be used on this mount without any problems. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXD2WL sets a new standard for performance and precision in the Vixen mount family.
The axis cross of the mount is with a photographic carrying capacity of 15 kg just 9.2 kg light and thus excellent for mobile observations . Moreover, the motors located in the lower part of the mount also act as counterweights. This reduces the need for additional counterweights.
The SXD2 Mount in Detail
Precision stepper motors and Micro-Step-Motion-Control system
The heart of the SXD2 are the precision stepper motors, which offer better performance and response than previous models. The Micro-Step-Motion-Control system boasts powerful yet very quiet drive properties, which are present both in fine movements and in fast swivels.
Built-in bearings
The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. As a result, the motors move much quieter than in previous models.
High-precision worm gears
High-precision processing technologies eliminate errors in the worm gears. The edges of both worms and worm wheels are particularly smooth, enabling very precise tracking.
Declination axis as counterweight
The massive motor units are built into the lower part of the declination axis, so the center of gravity of the SXD2 is below the intersection of the RA and DEC axes. This means you need fewer additional counterweights.
Latitude adjustment
The latitude can be adjusted between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium, and low latitudes); latitude scale in 2-degree steps; fine adjustment with a tangent screw head, approx. 0.8 degrees per rotation.
Built-in PFL-II polar finder with illumination
The built-in 5x20-mm polar finder with a 10° field of view features a 3-star alignment system.
This eliminates the tedious setting of date and time. The illuminated reticle with variable brightness and automatic shutoff is adjustable in 8 levels and is red illuminated. The adjustment accuracy is 3 arc minutes.The Wireless Module in Detail
The Vixen WiFi Adapter for EQ mounts enables you to control your Vixen mount via a smartphone or tablet. This allows you to navigate the skies wirelessly using the STAR BOOK Wireless app (free), instantly transforming your mobile device into a controller for the equatorial mount. The response delay of the mount, a major drawback of wireless connections, has been reduced to a level comparable with wired solutions.
Reduced power consumption compared to conventional controls with LCD monitors
The power consumption of the mount is reduced by up to 20%, thus allowing for longer observation periods than with conventional wired controls such as the STAR BOOK TEN.
Operation similar to the STAR BOOK TEN controller
The STAR BOOK Wireless App is structured similarly to the STAR BOOK TEN controller you might already be familiar with. Depending on the star chart settings, it includes up to 259,000 celestial objects. Simply tap on a celestial object in the object list to start the GoTo. The mount then automatically moves to this target and positions it within the telescope’s field of view. All the popular features of the STAR BOOK TEN are retained.
Convenient operation
While looking through the telescope, you control the mount by swiping on the app’s star map. With no buttons required, you simply glide your finger over the star map, allowing for easy operation of the mount.
Comprehensive astronomical data included
This includes data on easily observable celestial bodies such as Messier objects, NGC objects, IC objects, as well as the sun, moon, planets, comets, and dwarf planets.
High-precision alignment
Aligning with one or two stars already provides a fairly accurate positioning of the mount. Aligning with three or more stars allows for high-precision alignment of the mount for high magnifications. The objects are then precisely centered in your telescope’s field of view. The alignment information is stored and can be retained even when the device is turned off. By leaving the telescope in its current state after observing, without moving it, you can start the next observation with the automatic setup using the same settings.
Individual setting options
Like the STAR BOOK TEN controller, the app offers various individual settings such as backlash compensation, red night mode, autoguider, as well as variable GoTo speed and LED brightness. You can also set the timing of the objective tube reversal (Meridian Flip) as desired. Even if the object moves south during tracking, you can prevent the telescope tube from reversing.Important Information

A new 81 mm apochromatic refractor with high-performance Super ED glass (= SD). The advantage of these SD refractors is their short length and low weight.The FPL53 glass reproduces an extremely clear and sharp image due to an exceptionally high elimination of residual colour errors. The SD glass is designed to bring all rays of violet, red, blue, yellow and green together very precisely on the same plane. Thus, the special lens material reduces chromatic aberration across all colours.The new Vixen SD81SII no longer uses spacer plates, which leads to significantly better image quality, especially with bright stars. This means that there are no more spikes on the stars in photographic images, which were otherwise produced by the spacer plates. You will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp and with an extremely high contrast. Observe the ring planet Saturn or the cloud bands on Jupiter.But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed impressively.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, this refractor allows illumination with a 44 mm image circle for full-frame SLR cameras.The older ED81SII, ED103S, ED115S refractors were originally designed for the visual observer or the photographer using APS-C cameras. However, the new SD series has been optimised for use with full-frame cameras by inserting new inner baffle rings.The large 60 mm focuser allows heavy cameras to be attached without tilting. The supplied flip mirror allows comfortable observation, even in unfavourable observation situations, and also offers a T2 thread for connecting a DSLR camera.Thus, observing in degree view or at a 90° angle is possible. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope.FEATURESObjective Lens: D=81 mm, multi-coated 2-Lens SD Apochromat without spacer plates No more spikes on the stars Focal Length: 625 mm (f7.7) Resolution and visual limit: 1.43 arcseconds; 11.3 Mag Light gathering capacity: 134x unaided eyesDimensions and weight: 90 mm dia x 585 mm, 3.6 kg Finderscope: XY Red Dot Finder II Adapter and connections: Adapter thread 60 mm and 31.7 mm for T2-ringConnection 50.8 mm and 31.7 mm socket with flip-mirror diagonal mirrorPhotography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor telescope SD81SII Tube rings Flip mirror system Carrying handle Dovetail rail Red dot viewfinder

The new BRESSER Nebula 6 EQ/AZ Wifi-Network Mount is a precise and quiet telescope mount – ideal for astrophotography. The controller box offers numerous central connection options for various accessories such as cameras, filter wheels, and motor focusers via USB (2.0/3.0), simplifying the setup of a professional astro-photography machine.
BRESSER relies on innovation paired with quality Made in Italy for this top-class product. The long-standing experience of the manufacturer in mount construction guarantees a high-end device with first-class functionality and highest reliability. Additionally, the in-house development team for hardware and software in Italy ensures quick response times in technical support and the adaptation of new device drivers. True to the motto "Professionals at work!"
The mount is controlled via pre-installed web app software, accessible via Wifi and an Ethernet cable connection. The philosophy behind the Nebula GoTo system is to provide the user with a control system independent of a normal PC, which can be remotely controlled in all its functions via a smart device such as a mobile phone or tablet. However, this does not exclude the traditional use of computers of all types and brands, which can be connected to the system either wired or wirelessly.
The BRESSER Nebula GoTo System Controller is a Raspberry Pi 4 microcomputer, which allows complete control of the setup (mount, camera, etc.) without the need for any other external device. The BRESSER Nebula GoTo system is already equipped with all Linux-based applications necessary for performing all astrophotographic functions.The existing INDI environment allows the control of almost all devices (cameras, filter wheels, rotators, including observatory domes), necessary for conducting local or remote astrophotography sessions.
The system also offers high flexibility for users who prefer to use traditional computer client applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools. This complete compatibility is ensured through the adoption of the Alpaca communication protocol, which allows the use of traditional ASCOM platform drivers for native INDI devices.
State-of-the-art mount construction
The BRESSER Nebula mounts are CNC-manufactured from stainless steel and aluminum. The simple and functional design is thanks to a renowned Italian mount manufacturer, who has designed and now also manufactures these fine BRESSER products 100%. So, look forward to a stable yet easily transportable mount, which despite its light weight of only 16 kg (including tripod) allows a high load capacity of up to 25 kg.
Visual Observation
For visual observation and direct use, control the mount with the hand control box included in the package. Alternatively, connect the Nebula 6 via WLAN directly to your smartphone or tablet and use the virtual hand control box. Of course, all adjustment parameters can also be adjusted via the web application. The user interface is deliberately simple and clear to ensure intuitive operation.
Astrophotography
Here, the Nebula mount shows its full strength. Whether mobile or stationary, remote capability is crucial. Connect your laptop or PC either via WLAN or with an Ethernet cable (recommended for faster data transfer) directly to the Raspberry-Pi control unit of the mount. Then use the pre-installed software Kstars/EKOS to control the mount and all external devices such as cameras, motor focus, filter wheel, etc. Alternatively, you can also directly control the unit with your own software. Applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools can be used without any issues.
2-in-1 Mount with EQ and AZ Mode
If required, the Nebula can be switched from the equatorial mode to the azimuthal mode. This is particularly advantageous for observing nature or tracking satellites. Thus, the mount can be used for various applications and is not limited to astronomy only.
Attachment of up to two optics
Would you like to adapt multiple optics? No problem. Simply use the option to replace the counterweight bar with another telescope. Use the second optic simply as a counterweight to the main telescope. Set the Nebula 6 to azimuthal mode, remove the counterweight bar, and screw on an extension adapter with a suitable second telescope clamp directly to the mount.

Experience a whole new view without vibrations and shaking from the free hand.
The ATERA H12x30 with 422 grams is one of the lightest binoculars with image stabilizer. Due to the strong vibration canceller effect, an extremely stable field of view is achieved even from the free hand. At higher magnification you can observe everything in detail, such as reading signs and lettering, recognize the structure of bird feathers, and the ATERA is also a great companion for astronomical observations of stars. Fewer vibrations in the field of view increase the visibility of object details and the comfort of observation.
The vibration of your hands often makes it difficult to see sharp objects, especially at high magnification. ATERA H12x30 features a vibration suppression mechanism with a 2-axis gimbal-mounted image stabilization mechanism. With a strong correction effect of the vibration correction angle of approx. 3 degrees(up, down, left and right), a stable field of view can be achieved even at a high magnification of 12x. Since the micro-vibrations are also eliminated, even the finest details can be seen.
Two standard AAA micro batteries are used for the power supply. As they are easy to get everywhere, safe operation is guaranteed even in remote areas. Thanks to a long operating time of up to 12 hours, you can concentrate on observation without having to worry about battery consumption. An automatic power-off function, which cuts off the power after 5 minutes, prevents unnecessary battery discharge.
By applying a complete multi-coating and an anti-reflection coating on all lens surfaces, the additional phase coating on the prisms, the light transmission and thus brightness of the image is drastically increased. All these features ensure low stray light and light loss and produce a particularly clear and high-contrast image.
A gently rounded shape that adapts to the hands, a focus ring that can be gently rotated by lightly touching it with just one finger, a simple design, a battery compartment that is away from the operating area, all designed for ease of use. The integrated battery cover effectively protects against loss.
The ATERA is delivered with a comfortable carrying strap and a protective bag for transport.

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.
