LUNT LS60FHa H-alpha double-stack solar filter

Spare part for Pressure-Tuner of MT and THa series H-alpha solar telescopes from LUNT SOLAR SYSTEMSFor example, if the O-rings have been changed on a Pressure-Tuner of a Lunt Solar Systems H-alpha solar telescope, the Pressure-Tuner can be re-greased with this grease. The grease can be applied to the piston with the O-rings and to the threads of the brass cylinder on the Pressure-Tuner. It keeps the Pressure-Tuner running smoothly and seals it.Please note:Do not use too much grease inside the brass cylinder. The grease must not get into the air passage at the bottom of the brass cylinder, otherwise the Etalon could be damaged in the worst case.FEATURESLithium grease with Teflon contentVery good sealing propertiesHigh adhesion and good corrosion protectionTemperature stable from -20 to +120° CelsiusConstant viscosity during temperature fluctuationsSCOPE OF DELIVERYSpare part: Grease for Pressure-Tuner of MT and THa H-alpha solar telescopes from Lunt Solar Systems

50mm H-alpha double-stack solar filter, for all LS50FHa filter-systems and LS60THa/LS60MT telescopes.This double-stack Etalon is compatible to all Lunt Solar Systems LS50FHa filter-systems and LS60THa / LS60MT telescopes. Adding this additional double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom (dependent upon used telescope). So you will have much more contrast and more details on the sun will be visible.Without blocking filter! Only for use as double-stack filter, or together with a additional available blocking filter. If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is <0.75 Angstrom.FEATURESAperture: 50 mmNo central obstructionBandwidth double stacked: <0,55 AngstromTuning: tiltable EtalonHousing diameter: 95 mmLength: 73 mmWeight: 0.7 kgFront thread: M90x1 female threadRear thread: M90x1 male threadSCOPE OF DELIVERYLS50FHa solar filterTransport caseInstruction manual

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-53 glass, 100mm aperture and 714mm 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 LS100MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 100mm free aperture (no central obstruction) and 714 mm 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 LS100MT 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. With the additionally available conversion kit (item number 0551430) the 3-lens apochromatic refractor can then be used as a normal telescope with 100mm aperture and 714mm focal length for observation and photography of the night sky. The FPL-53 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551430. Please note that the optionally available conversion kit 0551430 is absolutely necessary if the telescope should be used at night. More applications: With additionally available accessories the LS100MT offers even more possibilities! - Double-Stack The LS100MT 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-Light If 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 wavelength Certainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS100MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun. This makes the LS100MT a completely universal usable apochromatic telescope of highest quality!

Most people associate CO2 with one thing— it’s harmful effect to the environment. But it’s not just our environment that suffers as a result of carbon dioxide. We too need clean air for our well-being and health. In locations with high concentrations of people, this can lead to problems. The BRESSER CO2 air quality monitor Smile XXL supports you in preventing critical CO2, temperature and humidity values. It couldn’t be easier—all it takes is a quick glance at the extra-large LED display. The graphical display, with three different smiley faces and a bar scale, gives you an initial indication of the current CO2 load. The precise measured value is displayed in large figures below. The device also displays temperature and humidity, so that you have a complete picture of the air conditions at any time. The device impresses with a high resolution and rapid response time for highly accurate results. The best air quality made easy In areas with heavy workloads, such as hospitals, there is often insufficient time to carry out air quality measurements. In larger spaces too, such as storage halls and agricultural production facilities, it can be hard to keep track of things. In these situations, the carbon dioxide alarm is especially useful: Simply set the maximum value that meets your individual needs. The warning signal sounds as soon as this upper limit is exceeded. The device has an excellent power supply, with the mains adapter supplied enabling long-term continuous operation. With the BRESSER CO2 air quality monitor Smile XXL, you can breathe easily again.
