Warning notes
- General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
- 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.
- Do not expose the device to high temperatures.

BRESSER T2 Extension Tube Set
€29.00*
Set of 5 extension tubes with T2 thread on both sides for exact distances and secure hold of cameras for astrophotography. Also comes with SC to T2 thread adapter.In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not sufficient, as specific distances must also be observed. This is especially important when using correctors, reducers or flatteners. This extension tube set, which consists of 5 mm, 7.5 mm, 10 mm, 15 mm and 30 mm tubes, will allow you to obtain almost any distance using the corresponding combination. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.Most telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2 plug-in diameter (item no. 0510365).However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or RitcheyChrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SD to T2 thread adapter.FEATURES5 T2 tubes with lengths from 5 mm to 30 mmCombination of tubes allows you to obtain distances of 5 mm to 67.5 mmFor exact camera distances in astrophotographyDELIVERY CONTENT5x T2 extension tubes (5/7.5/10/15/30 mm)1x SC to T2 thread adapter

LUNT LS130MT/B1200 Multipurpose APO Telescope for Sun + Night-Sky
€10,990.00*

(15.46% saved)
Complete H-alpha Solar Telescope with 130mm aperture and <0.7 Angstrom bandwidth. With Feather-Touch focuser, advanced air-pressure tuning system, and B1200 Blocking Filter.The LS130MT is a triplet ED apochromatic refractor with modular design! The telescope can also be used for night sky observations, and with
the optional available accessories also for observing the sun in the
Ca-K wavelength and in White-Light!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 higher resolution compared to telescopes with smaller aperture allows the observer to dive into the fine details and surface phenomena of our ever-changing Sun. The higher resolution allows higher magnifications, bringing the fine details of the Sun to life in the eyepiece or on the screen.An internal Etalon filter with the innovative air pressure tuning System Pressure Tuner achieves a bandwidth of <0.7 Angstroms. The 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 adjust to the H-alpha line. The pressure tuner guarantees an homogeneous image without central obstruction and a permanently protected etalon without wear. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved by a 2" Starlight-Instruments Feather-Touch focuser with 1.5" travel and 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 CCD chip. We recommend a LS130MT with B1800 blocking-filter by using cameras with middle or large sized CCD chips, at very large CCD chips the B3400 blocking-filter.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection.Also the LS130MT telescope is upgradeable with the additional available DSII double-stack system (item no. 0551690). The optional DSII system is a internal double stack module with Pressure Tuner, that provides a bandwidth <0.5 Angstrom. More details on the solar surface will become visible by reducing the bandwidth.Modular design:The H-Alpha Etalon system can be easily removed from the telescope. The 3-lens ED Apochromat can be used as a normal telescope for observation and imaging of the night sky.Also available is a Ca-K module (item number 0551697) specially developed for the LS130MT. This also allows to observe the sun in the blue calcium wavelength.A Herschel-wedge (item number 0558201) can also be used for observing the sun in white light.This makes the LS130MT a completely universal usable telescope!FEATURESTriplet ED apochromatic refractor, FPL-51Aperture: 130mm (no central obstruction)Focal length: 910mmBandwidth: internal Etalon with <0.7 AngstromTuning: air-pressure tuning systemBlocking-filter: B1200 with 1.25" and T2 connectionFocuser: Starlight-Instruments Feather-Touch focuser with 10:1 reductionTwo tube rings with carrying handleDove tail bar with GP level for astronomical MountsWeight: 12.1kgLength with blocking-filter and dew-shield: 100cmLength without blocking-filter and removed dew-shield: 80cmSCOPE OF DELIVERYLS130MT multipurpose telescopePressure-Tuner systemB1200 blocking-filter in star-diagonal2" Feather-Touch focuserTube-extension for using without H-alpha EtalonTube rings with dove tail barTransport case (92x42x35cm)Instruction manual
