EXPLORE SCIENTIFIC TELRAD Base Plate

The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

Top viewfinder telescope with upright field, illumination, 90° view and pole viewfinder engraving - image sharpness and viewing behavior raise this viewfinder significantly above the level of the usual 8x50 viewfinder telescopes. The upright image field facilitates orientation. Multi-Coating on all surfaces. This polar finder is mainly intended for the observer with a transportable telescope. The 90° view facilitates operation, and with the help of the pole scale and the lighting, a telescope can be quickly and safely aligned to the celestial pole. The upright field of view makes the handling together with the high image sharpness a pleasant experience. The lighting is powered by two LR41 button cells.

The new BRESSER Weather Station 5-in-1 white combines in a unique way a compact design with an extensive information service. The very compact and multifunctional outdoor sensor requires very 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 included. The 5-in-1 outdoor sensor reliably transfers 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 these values can be read but can also be stored as data history. 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). In 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.
