Vixen VMC200L Maksutov-Cassegrain mirror telescope - optical tube

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. The Finder Scope and the Vixen Flip Mirror is not included in this version !

Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. 2-lens ED Apo telescope with FPL-53 glass, 80mm aperture and 560mm focal length - very good image quality for H-Alpha solar observation and also for observing the starry sky at night.With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B1800 blocking filter.Solar observing in H-alpha:The LS80MT/B1800 is a complete telescope for observing the sun in H-alpha light, with 80mm free aperture (no central obstruction) and 560mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch R&P focuser with 10:1 reduction.Blocking-filter is the B1800. The B1800 is very good for visual solar observing and also for photography.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-Alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. With the additionally available conversion kit (item number 0551330) the 2-lens ED Apo refractor can then be used as a normal telescope with 80mm aperture and 560mm focal length for observation and photography of the night sky. The FPL-53 doublet lens offers an low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551330.Please note that the optionally available conversion kit 0551330 is absolutely necessary if the telescope should be used at night.More applications:With additionally available accessories the LS80MT offers even more possibilities!- Double-StackThe LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS80MT a completely universal usable ED Apo telescope of very good quality!FEATURES2-lens ED APO refractor, FPL-53Aperture: 80mm (no central obstruction)Focal length: 560mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B1800 with 1.25" and T2 connectionFocuser: R&P with 10:1 reductionTwo tube-ring with handleSol-Searcher installed inside handleDovetail bar at GP-level for astronomical mountsWeight: 4.95kgLength with blocking filter and dew-shield: 62cmLength without blocking filter and removed dew-shield: 50cmSCOPE OF DELIVERYLS80MT Multipurpose TelescopePressure-TunerB1800 blocking filter in star-diagonal housing2 inch R&P focuser with 10:1 reductionTube rings with dovetail bar and sol-searcherTransport case (78x33x23cm)Instruction manualConversion kit for observation of the starry night sky (0551330) not included!

SXP2 mount with R200SS reflector telescope. This telescope set has everything you need to observe the night sky.It includes a telescope, a mount with automatic tracking, a tripod and two eyepieces.The SXP2 mount comes with the new STARBOOK TEN control technology and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars.The R200SS was designed for photography and produces a sharp and high-contrast image with a rapid aperture ratio of f4. Thanks to the fast focal ratio, you can obtain quick and stunning images of galaxies and nebula.The telescope set also offers outstanding visual performance and produces sharp images without chromatic aberration. It also produces impressive images of the moon's craters and Saturn's ring system.The mount can be operated fully automatically and finds celestial objects automatically.The SXP 2 mount in detailStrong mount housingCompared with previous models, the new SXP2 mount features larger bearings in order to increase the accuracy and load capacity.The mounting housing is made from a stronger material than the previous SX mounts.The equatorial head is clamped into a fork in order to increase the stability of the polar alignment wedge.Precise tracking with P-PEC functionThe SXP2 mount comes with the modern STARBOOK TEN control system. This includes a P-PEC function for precise tracking. PEC stands for ''Periodic Error Corrections'' and corrects errors in the mechanics which lead to periodic errors in the gear systems. The P-PEC function, which is based on the PEC function, is designed for the SXP2 equatorial mount. The P-PEC function saves the records of corrections, even after the power supply to the mount has been switched off. It is not necessary to re-enter the data each time, which enables a quicker setup and more precise tracking.The belt drive system minimizes backlash and noiseConventional motor-driven systems on equatorial mounts use gear wheels, which are driven by the motor. However, this design generates backlash under the gear wheels, which can lead to inaccuracies.To avoid these errors, the drive was converted to a belt drive system. This drastically reduces the backlash of the gear unit, as well as the noise generated by the drive system. It also ensures a quicker reaction when corrections are required.16 bearingsThe mechanical parts contain a total of 16 bearings.The SXP2 mount uses a set of tapered roller bearings for the RA axis in order to provide additional stability for more precise tracking.Stable polar alignment wedgeThe SXP2 mount uses the same fork as the heavy AXJ mount. This new construction enables a quick and stable configuration of the latitude setting.Simple and precise polar alignment via reference starThe 6x20 polar finder scope is pre-installed. This allows the user to configure the polar alignment (for both the northern and southern hemispheres). The polar finder scope has a variable illuminated reticle with an automatic power-off function. The brightness can be adjusted in 8 levels so that the user can configure the desired brightness.The polar finder scope can be configured directly via three reference stars and can reach an accuracy of up to 3 arc minutes.Variable mount headThe mount head has a diameter of 35 mm and features 8 threaded holes for M8 screws spaced at 45 degrees. An optional accessory tray can be attached to the mount head directly or in combination with an optional mounting wedge for dovetail plates. The threaded holes on the mounting head can also be used to mount rails from other manufacturers. Modern STAR BOOK TEN controller with high-resolution colour display and built-in star chartThe STAR BOOK TEN controller is a modern control system with a high-resolution colour monitor.The STAR BOOK TEN system contains more than 272,000 celestial objects, including 260,000 stars from the SAO catalogue, 109 Messier objects, 7840 NGC objects and 5380 IC objects, as well the soon, moon and planets. Objects can be accessed by name, and information such as images and data can be defined separately.A combination of innovative, elegant design and user-friendly featuresThe improved design of the stable and rigid mount body, which features precise tracking with a P-PEC function and STAR BOOK TEN control system, offers a highly precise, easy to use mount that is guaranteed to please astrophotographers and observers.Special motor mount for lighter counterweightThe heavy RA and DEC motor units are built into the bottom of the declination axis to ensure that the centre of gravity of the equatorial head is below the RA and DEC axis. This enables the declination body to function as a counterweight. Thanks to the flat mounting head, the mount can be balanced with a significantly lighter counterweight.Retractable counterweight barThe counterweight bar is made from solid stainless steel with a thickness of 20 mm, and enables the use of all counterweights from the SX and GP mount series. The counterweight bar is housed in the declination body.The Vixen R200SS reflector telescope in detailThe R200SS features very fast f4 200 mm optics with a parabolic primary mirror and produces extremely sharp images with no chromatic aberration. A special layer made using state-of-the-art technology provides an optimal surface for observing and photographing deep-sky objects.The large aperture and short size make this device ideal for astrophotography of nebulae, star clusters and comets. The use of an optional coma corrector provides a sharp image until the edges of the field of view. The focuser features a 60 mm thread to enable the use of 2-inch eyepieces with an adapter.Vixen has developed a unique aluminium vacuum evaporation system that produces extreme precision mirror surfaces. The revolutionary Vixen system allows for controlled coating of the primary mirror for greater accuracy. This coating is used on both the VC200L and the R200SS.FEATURES Mirror: 200 mm (8 inches) Focal length: 800 mm f4Resolution and limiting magnitude: 1.01 arc seconds; 13.3 magLight-gathering power: 816 xDimensions and weight: 232 x 600 mm, 6.9 kgAdapter and connections: 31.7 mm sleeve, 60 mm threadDELIVERY CONTENT SXG-HAL130 tripodSXG half-pier2 counterweights (1.9 kg and 3.7 kg)7x50 finder scopeCarrying strapDovetail barDovetail adapterFolding mirrorSLV 20 mm and SLV 5 mm eyepieceSXP2 GoTo mount with Star Book Ten controllerPolar Axis Scope PFL-2

Highly corrected 127 mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5'' high-precision HEXAFOC focuser. NEW: Now with hybrid viewfinder shoe to accept different viewfinder holders. 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 Alu Hex represents another major improvement in this field - the overall correction (colour 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 65 mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors.

Ultra Light Dobsonian 305mm GENERATION II - with completely redesigned and improved construction.No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 305mm aperture gathers more than 1800-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.Dimensions for mobile use: Rockerbox 450mmx450mmx320mm; Mirrorbox 380mmx380mmx300mm; Trusses approx. 980mmEyepiece Height while pointing at zenith approximately 1,4m.12“ Net total weight: 32,1 kg; 12“ Mirror Box: 18,9 kg; 12“ Secondary cage +Rockerbox: 10 kg; 12“ 4 Pairs of trusses: 1,8kg; 12“ Altitude Wheels: 1,4kg ; Focuser thread: M54 x 0.75 mm ; Backfocus: 45mm behind the 2" eyepiece holder. 35mm when the 1.25" adapter is mountedSPECIFICATIONS Truss-Dobsonian Telescope in full Aluminium constructionNEW: Slider bearings made from TEFLON und GFK for smooth and precise movementNEW: Improved main mirror cell with completely redesigned mechanicsNEW: Altitude bearings with new designed brake and friction systemNEW: Larger feet to improve stabilityNEW: Universal finder slot to enable an easy finder upgradeNEW: Counter-weight system included - 2 x 1.0 kg NEW: Quick-lock fasteners with new springloaded design for comfortable useNEW: Powder-coated yellow altitude wheels to improve durabilityNEW: Laser engraved central mark on main mirrorSCOPE OF DELIVERYTruss Dobsonian TelescopeLED finder with standard finder slotStray light shield for secondary cageMain mirror collimation toolBattery compartment with bag for fansCounter-weights 2 x 1.0 kgExtension tube for focuserReducer 2"/1.25"Manual
