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.Excellent for entering into the hobby of astronomy: 90mm aperture delivers 200 times more light than the naked eye! Observe craters, valleys and rims on the moon from nearly 400,000km away just as you would look out of the window of a spaceship! The MESSIER AR-90 does not only provide highly detailed views of the moon: Gaze at the division of the rings of saturn millions of kilometers away or explore the Great Red Spot of Jupiter, a giant tornado in Jupiter's atmosphere. Watch the seasons on Mars and find the sickle of Venus. The MESSIER AR-90 gives you images that are many times brighter than the instrument Galileo Galilei was using for his famous explorations almost 400 years ago.

Maksutov Newton MN-152 David H. Levy Comet Hunter Telescope Highly corrected optic for wide-field observation and astrophotography. Developed in collaboration with the famous "comet hunter" David H. Levy. The Maksutov-Newton system does have some pros and cons respectively to the classical newtonian design. Apart from the higher price the main disadvantage is the higher weight - the thick corrector lens at the front is the cause for this. The main advantage of the Maksutov-Newton compared to the classical newton is the sharpness of the field of view. Classical newtonian telescopes do show a sharp pinpoint star image only at the middle of the field of view - outside the optical axis they have a dominant abberation, the so called coma. This is inherent in the newtonian design, and therefore valid for all newtonian telescopes of all brands and not caused by manufacturing tolerances. Coma distorts the star image - the pinpoint star shows a tail, just like a small comet. This decreases sharpness and contrast considerably. The Maksutov-Newton shows a much sharper star image - for most applications the coma is not visible. This results in a high contrast image all over the field of view - for visual observations and for astrophotography with DSLRs alike. This makes the Maksutov-Newton a ideal all-purpose telescope, that is able to show a sharp field without the need for additional correctors.

With the BRESSER 11-Day 4Cast CV WiFi Weather Station 7-in-1 you’ll never find yourself left out in the cold by the weather again. The weather station, with 7-in-1 solar outdoor sensor, supplements the on-site data with plenty of practical information from the ProWeatherLive platform. A special highlight: the extensive weather forecast, with the outlook for the next 11 days and a detailed overview of the next 24 hours. Information on local visibility and cloud cover also helps passionate amateur meteorologists to keep a close eye on the weather. You’ll always be up to date, whenever and wherever you are – choose to view your data, incl. max./min. values, conveniently on the clear display of the weather station, in the ProWeatherLive app or in a web browser. Environmentally-friendly and user-friendly – weather station with solar sensor Quick to install and connect to the base station, the 7-in-1 wireless sensor reliably supplies data measured directly on site, including temperature, humidity, wind speed, wind direction, precipitation amount, UV level and light intensity. Meanwhile, the power of the sun ensures smooth operation via the large solar panel. The measuring device needs about 4 hours of direct sunlight (100,000 lux) a day. There isn’t much sun around? Simply insert 3 AA batteries as a back-up during installation and they will take care of the power supply. A comfortable indoor climate with the WiFi weather station Outdoors, the weather station puts in a great performance with anemometer and rain gauge as well as thermometer and hygrometer, UV and light sensors. What about the climate indoors? A thermo-hygro sensor has been integrated into the base station so that you can always keep an eye on the indoor temperature and humidity. The trend display, which can be called up directly on the display, is perfect for preventing excessively dry air or mould. Trends you will be able to see include development of the room climate, so that you can respond by introducing fresh air or by humidifying if you need to. In addition, with ProWeatherLife, you can receive notifications when the indoor temperature and humidity change, as well as important weather parameters. Optional extensions for your WiFi weather station Want to adapt your weather station to your needs? No problem! It comes with a range of optional extensions through the following additional sensors (not included): Optional thermo-hygro sensors for indoor climate Optional soil and pool sensors for the garden Optional water detector and lightning sensors Optional PM2.5/10, CO2 and HCHO+VOC sensors for air quality For the perfect extensions, browse our BRESSER accessories to see which additional sensors are compatible (not included).

The EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector, reduces a compatible telescope's focal length by a factor of 0.7x (for around f/8) and 0.8x (for around f/10) respectively. The reducer/corrector not only reduces the focal length but also flattens the field. Although originally developed for the Explore Scientific ED-APOs 127mm and 152mm, the reducer can be used with many systems - for example with the Explore Scientific ED-APOs 102mm and 165mm (please note, this will not work on the Explore Scientific 80mm ED Apo refractors though). With certain telescope focal lengths, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. This unit comes with 3" barrel adaptor for direct focuser thread M54x0.75 (the standard focuser thread of the Explore Scientific Essential series of ED Apos) and T2 camera adaptor. This reducer/corrector features a free aperture of 65mm, so that it can be used even with cameras that have a large sensor - if the telescope allows for this. Note: As previously mentioned, this Reducer/corrector comes with a screw on ring, which fits the standard focuser thread of the Explore Scientific Essential series of ED Apos. For telescopes which are equipped with the 2.5" HEX Focuser, the optional screw-on adapter part no: 0510366 is needed. Other telescopes, not in the Explore Scientific range, with standard 2" push-fit focusers will need the Explore Scientific 2" Adaptor for 3" Corrector - part no: 0510364 to get this reducer correctly fitted. SPECIFICATIONS Reduces the focal length by 0.7x at f/8 Flattens the field for astrophotography Developed for ED127 und ED152 APO telescopes Also fits Explore Scientific ED102 and ED165 telescopes - and others Free aperture: 65mm Inner thread for telescope adaption: M76x0.75mm Outer thread for camera adaption: M72x0.75mm 3" focuser barrel adaptor included Adaptor for Explore Scientific focuser M54x0.75mm included T2 camera adaptor M42x0.75mm included Diameter: 78.5mm; length: 100mm Length without adaptors: 52mm Weight without adaptors: 530g What's Included Reducer/Flattener 3" focuser barrel adaptor Adaptor for Focuser M54x0.75mm T2 camera adaptor M42x0.75mm Dust caps
