Vixen Fluorit refractor FL55ss

Highly corrected 102mm air-spaced triplet apochromat (with three lenses) and carbon fiber tube and a 2.5" high-precision HEXAFOC focuser.   Apochromats are the ultimate choice in small to medium sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 CF Hex represents another major improvement in this field - the overall correction (color and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0,97 indicating a level of correction that is absolutely top of the line.This excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible. The high contrast and sharpness of the image provide breathtaking views of large objects like the North america nebula or the Andromeda galaxy as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing created a telescope that offers observing joy on the highest level. This does not only qualify this telescope as the ideal travel scope, it is also the perfect choice for fast observations and for astrophotography. The excellent 2,5" HEXAFOC focuser with 10:1 reduction is perfect for this - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors. These very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors we do offer in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack&Pinion Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)) Professional Line: HOYA FCD-100 Glas lens, AL/CF-Tube, 2.5" HEXAFOC Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 102mmFocal Length: 714mmFocal ratio: f/7.0Design: Apochromat with three lenses, two air spaces and FCD-100 glassWeigth: 3,3kg , lightweight due to carbon fiber tubeBackfocus: 150mm above 2" adaptorDesign: Apochromat with three lenses, two air spaces and FCD-100 glassSCOPE OF DELIVERYOptical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handleExtension tubes for focusser (2pcs)Dust caps for front-lens and focuserUniversal finder slot 

SX2WL R200SS telescope set, complete with GoTo mount, tripod and eyepiecesThis high-quality Newtonian telescope set impresses with its large 200 mm aperture and fast focal ratio for photography. The telescope is manufactured in Japan and scores with its excellent workmanship, sharpness and contrast performance. The advantage of this telescope is its low weight and short focal length, making it ideal for larger deep-sky objects. You will be amazed when you use it to observe the surface of the moon with its craters or Saturn with its ring system. On a good night, many smaller details will be visible in the cloud bands on Jupiter, such as the large red spot on the planet. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting fainter objects. The brighter globular star clusters can be easily resolved into individual stars. The fast focal ratio of 1:4 makes this telescope perfect for photography. You can therefore get a great photo very quickly and don't have to choose endlessly long exposure times. You can optimise the image quality with the optionally available flattner Art. X000150. This flattner (not included) optimises the image right into the corners of a full-frame DSLR camera. The large 60 mm focuser also allows even heavy cameras to be attached without tilting. The sturdy metal tripod enables vibration-free mounting of the telescope and mount even in windy weather. The ultra-modern SX2WL mount is simply operated via a Wi-Fi module with your smartphone or tablet.By simply controlling the mount with your smartphone or tablet and using the free STAR BOOK Wireless app, you can easily use sky navigation functions such as automatic GoTo panning for many celestial objects. By eliminating the conventional LCD display (STAR BOOK TEN), the power consumption on the mount is reduced by up to 20%, thus enabling longer astronomical observation and astrophotography.When you touch the desired celestial object on the star chart, it is automatically pointed into the telescope's field of view and tracking begins.NOTE: An existing STAR BOOK TEN or ONE controller 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 SX2WL brings a new standard of performance and precision to the Vixen mount family.With a photographic load capacity of 12 kg, the axis cross of the mount is just 7 kg light, making it ideal for mobile observations. In addition, the motors mounted in the lower part of the mount also serve as a counterweight and the mount therefore requires fewer weights for balancing.The SX2WL mount in detailPrecision stepper motors and micro-step motion control systemAt the heart of the SX2 are the precision stepper motors, which offer better performance and response than previous models. The micro-step motion control system scores with powerful yet very smooth drive characteristics, which are present in both fine movements and fast pans.Built-in bearingsThe 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 more smoothly than in previous models.High-precision worm gearsHigh-precision processing technologies eliminate worm gear errors. The running surfaces of the two worms and worm wheels are manufactured to be particularly smooth, enabling very precise tracking.Declination axis as counterweightThe massive motor units are installed in the lower part of the declination axis so that the center of gravity of the SX2WL is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights.Latitude adjustmentThe latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable in +/- 15 degrees per zone, for high, medium and low latitudes); latitude scale in 2-degree increments; fine adjustment with a tangent screw head, approx. 0.8 degrees per turn.The wireless module in detailThe Vixen Wifi adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. With the smartphone app "STAR BOOK Wireless" (free of charge) you can navigate the sky without any cables. The "STAR BOOK Wireless" smartphone app transforms your smartphone or tablet into a control unit for the equatorial mount in no time at all. The response delay of the mount, which is considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired connections.Reduced power consumption compared to conventional controllers with LCD monitorThe power consumption of the mount is reduced by up to 20%, allowing longer observations than with conventionalwired controllers such as the STAR BOOK TEN.Operation similar to the STAR BOOK TEN control unitThe STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN control system. Depending on the star map setting, it contains up to 259,000 celestial objects. Tap on a celestial object in the object list and start the GoTo.The mount will now automatically move to this target and bring it into the telescope's field of view.All the popular features of the STAR BOOK TEN are retainedConvenient operationWhen looking through the telescope operate the mount by swiping on the app's star chart. As there are no buttons, simply slide your finger over the star chart to operate the mount conveniently.Extensive astronomical data includedIn addition to data on easily observable celestial bodies such as Messier objects, NGC objects and IC objects, this also includes the sun, moon, planets, comets and dwarf planets.High-precision alignmentBy aligning the mount to one or two stars, you can already achieve fairly precise positioning of the mount. By aligning to three or more stars, you can achieve high-precision alignment of the mount for high magnifications. The objects are then approached precisely and centrally in the field of view of your telescope. The alignment information is saved and can be retained even when the device is switched off. By leaving the telescope in its current state after completing an observation without moving it, you can start the automatic installation with the same settings for the next observation.Individual setting optionsAs with the STAR BOOK TEN controller, the app offers various individual settings, such as gear backlash compensation, night mode in red, autoguider, variable GoTo speed and LED brightness. You can also set the timing of the reversal of the objective tube (meridian flip) as required.Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing.Important information: Cannot be used on old SX mounts with the old blue star bookTechnical informationCPU with 32-bit CISC processor 120 MHzThe unit is connected to the mount via a D-SUB 9PIN connector as is the STAR BOOK TEN.It has a 6-pin, 6-wire modular connector for external autoguider operation.Supported operating systems are Android 6 or higher, iOS 9.0 or higher, WLAN standard: IEEE 802.11b/g/n・Details of the R200SS TelescopeThe f/4-200 mm optics of the R200SS impress with a great light-gathering capacity and are equipped with a parabolic primary mirror, thus delivering extremely sharp images without chromatic aberration. A special coating (state-of-the-art technology) provides the optimal surface for the observation and photography of deep-sky objects. Vixen has developed a unique aluminium vacuum coating system that produces extremely precise mirror surfaces. This revolutionary Vixen system allows for greater precision through the controlled coating of the primary mirror. This coating is also used in the VMC200L/VC200L, in addition to the R200SS.With its large aperture and short focal length, the R200SS telescope is ideally suited for astrophotography of nebulae, star clusters, and comets. The use of an optional coma corrector (not included) enables sharp imaging right to the corners of a full-frame DSLR camera. The eyepiece drawtube is equipped with a 60-mm thread for 60-mm adapters for various applications.FEATURESTelescope R200SSVery fast 200 mm f/4 optics Focal length: 800 mmResolution and limiting magnification: 0.58; 13.3 Light gathering capacity: 816x Dimensions and weight: 232 x 700 mm; 5.3kg Adapters and connections: 31.7 mm receptacle, 60 mm connection Backfocus: 72.5 +/-5 mm Made in JapanSX2WL mountRA Gear rim: 180 teethDEC gear rim: 180 teethBearing: Carbon steel / Decl. 35 mm, RA 40 mm thicknessFine height adjustment: 0° to 70°, (fine adjustment +/- 15°, height)Counterweight rod: 20 mm diameterAzimuth adjustment: Fine worm adjustmentPower supply: DC12 V; 0.4~1.7 AMaximum load: 12 kg, photographic, without counterweightCounterweight: 1x 1.9 kgTripod connection: 45 mm spigotDimensions: 36 cm (H) x 12 cm (W) x 36 cm (L)Weight: 7 kg, without counterweight32-bit CISC processor 120 MHzOperating system: Android 6 or higher, iOS 9.0 or higherConnection: D-SUB 9PIN plugAutoguider input ST4Power consumption SXD2WL+Wireless unit: DC12V / 0.3-2.0 A (load 10 kg), 0.4-2.2 A (load 15 kg)SCOPE OF DELIVERYSX2WL mountWireless unitCounterweight: 1.9 kg (2 pcs)Mounting toolCigarette lighter cableR200SS Newton telescope2 eyepieces: SLV20mm and SLV 5mmTube ringsDovetail mount7x50 finder scope  SXG aluminum tripod

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.

NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation. The BRESSER Messier NT-203 with a parabolic main mirror provides you with images that a few years ago were impossible in this price class. Modern production technology lets you track the shadows of Jupiter's moons on the planet; the amount of structure and details on the surface of the planet is breathtaking. But the Messier NT-203 is not only great for planetary work: Detect details in faint distant galaxies and let the glow of nebulae takes you to a journey into the depth of the Milky Way. The Messier NT-203 provides you with images from the remains of giant exploded stars and gives you a view into the nursery of new stars. Let this big scope take you away to the beauty of the universe! Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore, we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.
