Vixen Quick Release L-Bracket (Refurbished)

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.

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. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B600 blocking filter.Solar observing in H-alpha:The LS60MT/B600 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm 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 Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS60MT with B1200 blocking-filter by using cameras with middle or large sized CCD 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. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror or other accessories at the R&P focuser, the back focus is 135mm.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. 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 LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B600 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB600 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual

The BRESSER WSC Wi-Fi Weather Station with a 5-in-1 multi-sensor is the perfect way to keep track of your local weather. The compact base station comes with a stylish 14.5 cm (5.7”) colour display that shows you your very own weather report. Once you have connected to the wireless sensor, the station displays precise local measurements for the outdoor temperature, humidity, wind speed, wind direction and rainfall. It also features an eco-friendly design: to prolong the battery life, the outdoor sensor has a solar panel. Setup and sharing weather data made easy – with the WSLink app Theweather station with a built-in rain and wind gauge is very easy to configure: with the WSLink app, you can set up the Wi-Fi connection, time server and weather data calibration in no time. If you want to share your weather data and access it remotely, you can connect the weather station to a weather platform: the WSLink app has links to the popular providers Weather Underground and Weathercloud. An additional platform – such as the German-language portal AWEKAS, can be added manually. The app allows you to connect to your preferred weather server quickly and easily. Wi-Fi weather station – the perfect device for personalised weather data The base station also displays several other readings on the stylish display. If you’re wondering whether to wear a rain jacket or a T-shirt, simply take a look at the weather forecast and the feels-like temperature, which is calculated based on the wind speed, temperature and humidity measurements. If you want to know how strong the wind is, the Wi-Fi weather station can calculate gusts and the average wind speed, as well as the current wind speed on the Beaufort scale. It also displays the precise air pressure, as well as a trend indicator that can be used to draw conclusions about the latest meteorological developments. Indoor climate and more – clever features for your home The weather station can also help you to maintain an optimal indoor climate. The built-in thermo-hygro sensor measures the indoor temperature and humidity and displays the recent trend. If you’re not sure when to ventilate your room, the high/low alarm for indoor/outdoor temperature and humidity can help you to prevent mildew and excessively dry air. The weather station can also alert you when it detects high wind speeds, heavy rainfall and steep drops in air pressure. And thanks to the maximum/minimum memory, you can keep an eye on the changes in the weather over an extended period. In addition, the display shows you the time, date, day of the week and moon phase. And for early mornings, there is a built-in alarm function with a snooze button.
