The new BRESSER Weather Station 5-in-1 combines in a unique way a compact design with an extensive information service. The very compact and multifunctional outdoor sensor requires only little space and thus can be placed almost anywhere. A pipe clamp and screws for the attachment at poles (pipe diameter of about 25-33 mm) as well as a stand are already included!The 5-in-1 outdoor sensor transfers reliably all measured values for wind speed, wind direction, humidity, temperature and precipitation rate to the base station. On the clearly structured display of the base station not only these values can be read but also a multitude of history data. The latter allows the internal storage and evaluation of measured data over a period of 24 hours. From the collected measured data, the weather station calculates a very reliable local weather trend forecast for the next 12 hours, depicted by six graphic symbols on the display. For minimum and maximum values an individual alarm can be programmed, which gives an acoustic and a light signal when the defined value is reached. For outside temperatures of -3 °C and below a special alarm for frost/ice warning can additionally be activated.A poor indoor climate often involves health risks especially for children and the elderly. The BRESSER Weather Station 5-in-1 offers you a smart feature to deal with this. The indoor climate indicator informs steadily about the indoor climate with a symbol.Furthermore the BRESSER Weather Station 5-in-1 features a radio controlled time and date setting (DCF time signal). Already a few minutes after switching the device on the current Central European Time (CET) and the date with weekday are displayed automatically. For the “moonstruckers” also the different phases of the moon are shown. An alarm function with snooze mode is also integrated.FEATURESColour-display5-in-1 outdoor multi sensorInside temperature (°C/°F) and humidityOutside temperature (°C/°F) and humidityWind direction and speedGraphical weather trend display (12 hours)Beaufort index (scale for the classification for wind speeds)Precipitation rate with history (day/week/month)Air pressure with history (24 hours)Heat indexDew pointRadio controlled time and date settingPhases of the moonAlarm functionIce/frost warningHi/Lo-AlertMin/Max memory (up tp 24 hours)LED background light, amberSCOPE OF DELIVERYBase station5-in-1 Multisensor with mounting materialPower plugManual
Take a look through the new Vixen BT-81S-A binoculars. You will be impressed when you use them to observe gas nebula, star clusters or comets.
The magnesium fluoride coating reduces chromatic aberration and the large aperture of 81 mm ensures a razor-sharp, contrast-rich image.
The BT-81S-A binocular telescope set weighs 4.1 kg, is portable and also exceptionally suited for nature observations.

BRESSER 30mm Plössl Eyepiece 1,25" (31,7mm)
Since years a well known and approved Plössl eyepiece. Ideal to improve the performance of your telescopes for a low budget price.
All the BRESSER Plössl eyepieces provide sharp and high-contrast images because of the 4-lens design. All lenses have fully-multicoated surfaces which prevents reflections efficiently. Every eyepiece is equipped with a foldable rubber eyecup to avoid straylight from the sides and the inner eyepiece shaft is carefully blackened as well. Housing and eyepiece shaft are completely made from metal - no plastic is used. Filter thread for use with colour- and nebular filters is also available.
All these Plössl eyepieces offer a much better image quality than all the very simple made Kellner and Huygens eyepieces.
FEATURES
Focal length: 30 mm
Field of view: 50°
Lens-Design: 4 lenses in 2 groups , fully-multicoated
Housing material: completely made from metal
Rubber eyecup: YES, foldable
Filter thread: YES

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.The BRESSER Messier 8'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. The optical diameter of 203mm (8'') does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. With that telescope those objects are beginning to show structures: globular clusters are no longer only fuzzy blobs, but are resolved into masses of individual stars. Nebulae, that can only be barely detected in smaller scopes, reveal structures within. The telescope is setting a new standard in versatility: the excellent Hexafoc focuser boosts a free diameter of 65mm (2,5'') so that you do not have vignetting in big widefield eyepieces that is caused by smaller focuser barrels. The big altitude wheels handle those big, heavy eyepieces without problems - and when you intend to load even more (like a binocular viewer with two eyepieces) then you can move the tube in its tube rings and achieve balance within seconds. The excellent rigidity of the focuser makes focusing a snap - even for astrophotography. This is another virtue of this highly versatile telescope system: you can remove the altitude wheels from the tube rings, attach a dovetail and use the optical tube on a equatorial mount for astrophotography - in minutes. The focuser is handling even heavy cameras tilt and shifting-free. You are extremely demanding in your image sharpness? No problem - with the optional 10:1 gear reduction sharp images are easy. If you consider, that the focuser is that part of the telescope that is used most often, you will recognize the quantum leap this Hexafoc represents in a telescope of this price range.
With the included standard accessories (6x30 finder and 25mm SPL-eyepiece) the telescope is ready for observing.
If you need to transport or store the telescope as compact as possible you will like this: the rocker box of the 8'' BRESSER Messier assembles and disassembles extremely easy and fast due to the use of metal standard furniture fasteners. So you can transform the bulky rocker box into a handy flat package of boards.
This telescope is setting a new standard in usability, versatility and performance in its price class.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.
