LUNT LS300THa/B3400 H-alpha solar telescope

SXP2 mount with VC200L 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 controller and the PFL-II polar viewfinder, which allows you to configure the mount quickly and easily via reference stars. The VC200L was designed for photography and renders a sharp and high-contrast image to the edges of the camera chip. It produces stunningly sharp images of the 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 VC200L in detailAstrophotographers 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.FEATURES Mirror: 200 mm (8 inches) Photographically optimised system with flattenerFocal length: 1800 mmResolution and limiting magnitude: 0.58 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 thread109 Messier objects, 7840 NGC objects and 5380 IC objectsModern controller with high-resolution monitorIntegrated star chart and moon programBuilt-in autoguider input (ST4 port)DELIVERY CONTENTVC 200 telescopeSXP2 mountSTARBOOK TEN controllerMounting toolSXG-HAL130 tripod2 counterweights (1.9 kg and 3.7 kg) 7x50 finder scope Folding mirror Carry handle Dovetail barDovetail adapterV 20 mm and SLV 9 mm eyepiece

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. 3-lens apochromatic telescope with FPL-51 glass, 130mm aperture and 910mm focal length - excellent 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 LS130MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 130mm free aperture (no central obstruction) and 910mm 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 LS130MT with B1800 blocking-filter by using cameras with middle or large sized sensor chips, at very large sensor chips the B3400 blocking-filter. 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. Then the 3-lens apochromatic refractor can be used as a normal telescope with 130mm aperture and 910mm focal length for observation and photography of the night sky. The FPL-51 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the R&P focuser of the telescope. Please note that the optionally available conversion kit 0551696 is only absolutely necessary for the LS130MT version with B3400 blocking filter if the telescope is also to be used at night. The conversion kit is not required for the versions with B1200 and B1800. More applications: With additionally available accessories the LS130MT offers even more possibilities! - Double-Stack The LS130MT telescope can optionally be upgraded with the additionally available double-stack module LS130MT/DSII (item number 0551690). The DSII system is a internal double-stack module with Pressure-Tuner. 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-Light If the H-alpha unit has been removed, of course either a sun filter can 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 wavelengthThe additionally available "LUNT Ca-K Filter Module for LS130MT" (item number 0551697) can be used on the LS130MT to observe and photograph super-granulation and other effects visible at this wavelength on the sun. This makes the LS130MT a completely universal usable apochromatic telescope of highest quality!
