AP-A80Mf telescope set with mount, tripod and eyepieces The A80Mf refractor is an ideal entry-level model for beginner astronomers who value high-quality optics. Thanks to Vixen's quality controls, the 80 mm lenses are produced to an outstanding quality standard. The refractor comes with two Plössl eyepieces (6.3 mm and 20 mm) and a 90° star diagonal.The A80Mf is ideal for exploring the moon and the brighter planets.On moonless nights you can observe the Andromeda Galaxy or the Orion Nebula.The 6x24 viewfinder makes locating celestial objects quick and easy.The AP mount provides a secure, stable support for your telescope.Thanks to the slip clutch mechanism, the mount can be adjusted quickly to the target object.There is a wide range of optional accessories. The ADVANCED POLARIS mount is perfect for both beginner and experienced observers who require a lightweight travel mount.STYLISH DESIGNThe AP mount features an ultra-smooth finish without any projecting parts.Simply place your telescope on the mount and move it to the desired celestial object without having to loosen any clamps!QUICK POLAR ALIGNMENTThe slip clutches allow you to adjust the telescope to your target object easily - no more searching for adjustment clamps in the dark! An optional polar meter is available, which enables you to locate the celestial pole when it is hidden by trees or buildings.OPTIONAL POLAR FINDER SCOPEThe innovative polar finder scope provides a new way to polar align your telescope. Simply align the stars in the crosshair reticle with the same stars in the night sky. Polar alignment is achieved using 3 reference stars. The polar finder is illuminated to facilitate orientation and switches off automatically after 3 minutes to save battery power.STAR BOOK ONE CONTROLLERThe STAR BOOK ONE is a multifunctional and intuitive controller that tracks in the RA axis with a range of different speeds. The tracking options are designed for time lapse cameras at a wide range of speeds, including sidereal, lunar and solar rates. The controller also offers many useful functions such as backlash compensation, autoguider port, PEC and a built-in red LED light. The STAR BOOK ONE controller is designed for the AP-SM mount and is an integral part of the RA motor module.Power supply system for maximum mobility and comfort The motor module is powered by 4 standard AA batteries (alkaline batteries, not included). Rechargeable batteries (Ni-MH, Ni-Cd) can also be used. For extended periods of use, a external power supply (e.g. USB mobile battery or USB power adapter) can be connected to the USB Micro-B socket.APP-TL130 tripod The compact APP-TL130 tripod is adjustable between 60 cm and 130 cm and combines the portability of a camera tripod with the strength of an astronomical telescope tripod. The tripod can be switched between rubber and metal spikes to prevent floor damage in indoor spaces.FEATURESObjective lenses: 80 mm achromat, coatedFocal length: 910 mm (f11.4)Resolution and limiting magnitude: 1.45 arc seconds; 11.3Light-gathering power: 131xTotal weight: 11.3 kgFinder scope: 6 x 24 mmAdapter and connections: 42 mm for T-thread; 31.7 mm connectionIncluded accessories: 31.7 mm star diagonal, PL20 mm & PL6.3 mm eyepiecesPhotography: Prime focus and eyepiece projection Mount with 6 kg load capacity (photographic)DELIVERY CONTENT31.7 mm star diagonalPL20 mm & PL6.3 mm eyepiecesTube clampsDovetail holder6x24 mm finder scopeAPP-TL130 tripodAP mount1.0 kg counterweight

​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 B1200 blocking filter.Solar observing in H-alpha:The LS80MT/B1200 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 B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small sensor chip. We recommend a LS80MT with B1800 blocking-filter by using cameras with large sized sensor chips.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: B1200 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-TunerB1200 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!
