Product information "LUNT LS2HW 50.8mm (2'') Herschel-wedge"

Herschel-wedge / Solar-wedge for superior White-Light solar observing and imaging. For refractor-telescopes up to 150mm aperture, and with 2'' focuser. Complete system with installed ND3.0 filter.

Herschel-Wedges will be used to observe the sun in White-Light. Around 95 % of the sun light will be suppressed by the Herschel Wedge. The remaining sun light will be dimmed by a fix installed ND3.0 grey filter. Lunt Solar Systems Herschel-wedges are installed in a fully closed housing with integrated heat trap. There is no stray light escaping, therefore it is very safe.

The difference between Herschel-wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.
Furthermore, there is more safety at a Herschel-wedge than at a front mounted filter. A Herschel-wedge can not rip or become holes like a foil. And also it can not drop down from the telescope objective accidentally.

Only for use with refractor telescopes up to 150mm aperture:
Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel-wedge. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflector telescopes, become very hot by the concentrated solar energy and could be damaged.

Tuning the brightness:
Because the Herschel-wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced.
Polarizing filter not included. We recommend the BRESSER 2'' polarizing filter 4946465.

Warning notes

Safety instructions: There are certain dangers when observing the sun, regardless of the telescope used. Lunt-Solar-Systems places great emphasis on the safety of their products during manufacture. Your safety is the highest priority, and we ask that you carefully read the telescope manual before beginning solar observation. Please never disassemble the telescope! Never use it if it has been modified or damaged in any way! Always contact our customer service if you have any questions regarding the safety of your instrument. Never look at the sun with an unprotected eye or with a telescope not intended for solar observation! Never leave your telescope unattended while it is pointed at the sun! Other people who are unfamiliar with it might attempt to replace the block filter with another prism, unaware of how critical this filter is for safety. The components of Lunt-Solar-Systems telescopes are not interchangeable with those of other manufacturers. Lunt-Solar-Systems solar telescopes contain several different optical elements that have been precisely adjusted and mounted during manufacture. These systems require no maintenance. Never disassemble the telescope. Doing so will void the warranty, potentially leading to expensive repairs, and may cause future damage to your instrument, compromising your safety! Most Lunt-Solar-Systems telescopes and filters include a very sensitive optical component called an Etalon. These Etalons are built into the system to protect them as best as possible. Countless considerations have been made to ensure the best performance of this "heart" of every system, even under the daily stresses it inevitably faces, such as shocks and vibrations during transport or regular use. Nevertheless, it should never be dropped. Improper use of the telescope can damage the Etalon (not a warranty case) and render the system unusable until repaired. The instrument should always be stored in its original packaging or in the optional transport case (item number 0554010). Like any optical precision instrument, it should be stored in a dry environment. With proper care, you will enjoy your instrument for a lifetime!

LUNT LS7-21ZE Zoom Eyepiece 7.2mm - 21.5mm

Lunt Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun. Solar observation alone with these eyepieces without additional solar filters is not possible!FEATURESFocal length: 7.2mm - 21.5mm continuously adjustableBarrel size: 1.25 inch (31,7mm)Diameter: 47mmHeight: 82mmWeight: 170gEye relief: 15mmLenses / Groups: 7 lenses / 4 GroupsField of view: 53° at 7.2mm - 40° at 21.5mmSCOPE OF DELIVERYLUNT Zoom Eyepiece 7.2mm - 21.5mm

BRESSER Wi-Fi Colour Weather Station with 5-in-1 Professional Sensor, white

The new BRESSER Wi-Fi colour Weather Station with a 5-in-1 professional sensor offers a wide range of data in a compact device. The advanced, multifunctional outdoor sensor is easy to mount with the supplied mounting accessories. The outdoor sensor transmits measurements for wind speed, wind direction, humidity, temperature and precipitation to the base station at a frequency of 868 MHz. The clearly structured 5.7" colour display on the base station also displays a range of historical data. It enables internal storage and evaluation of the measured data over a 24-hour period. Using the measured data, the weather station calculates a very reliable local weather trend forecast for the next 12 hours, which is indicated on the display by graphical symbols. You can also use the Wi-Fi function to access your local weather data via Weather Underground. The Wi-Fi function also enables Internet time synchronisation and firmware updates. There is a programmable alarm function for maximum and minimum values, which can emit an acoustic alarm and light signal if either value is reached. A special frost/ice warning alarm can also be configured for outdoor temperatures below -3 °C. A poor indoor climate can pose a particular health risk for children and the elderly. The BRESSER Wi-Fi colour weather station offers a smart feature to help tackle this. The indoor climate indicator uses symbols to visualise the current status of the indoor climate. For fans of the moon, the display also indicates the various phases of the moon. An alarm with snooze function is also included. FEATURES 5.7" colour display for detailed time and weather information WiFi connection with internet time synchronisation Receives weather data from the 5-in-1 sensor and wireless thermo-hygro sensor over 868 MHz frequency Publish local weather station data on the internet via websites such as Weather Underground and Weather Cloud Time, calendar, day of the week and moon phase display Alarm function Ice/frost warning Indoor temperature (°C/°F) and humidity with comfort indicator Outdoor temperature (°C/ °F) and humidity display Displays gusts and average wind speed Precise wind direction display (16 directions) Precipitation quantity (hourly, daily, weekly, monthly, total precipitation) Weather forecast (sunny, partly cloudy, overcast, rain, storm, snow) Atmospheric pressure display Perceived outdoor temperature Weather index for dewpoint, windchill factor and heat index Min./max. memory (up to 24 hours) Alarm with LED indicator Weather calibration 3 different display brightness levels High/Low/Off 7 languages for days of the week Firmware updates supported Supports wireless 5-in-1 professional weather sensor (included) Supports up to 7 additional wireless sensors (optional) (item no.: 7009999) DELIVERY CONTENT Base station Professional 5-in-1 outdoor sensor with mounting accessories 100-240 V/50 Hz power adapter and cable
