Vixen NPL 4.0mm 4 Element Plossl Eyepiece 1.25"

​The Vixen SLV series are the modern take on the classic Vixen Lanthanum eyepieces. These eyepieces were legendary for their generous eye relief and precise nature, making them a firm favourite with planetary, lunar and double star observers. This 4mm is an excellent higher power eyepiece on shorter focal length telescopes, especially good for Lunar viewing - or for those trying to max out their longer focal length scopes for double star work. The SLV Series of Vixen Eyepieces feature a hexagonal shaped eyepiece barrel, long 20mm eye relief, and twist up click stop eyecup for adjusting to the most comfortable viewing. The SLV eyepieces feature high grade lanthanum glass, and deliver remarkably clear and high contrast star images to the edge of the viewing circle. The lenses are fully multicoated for high light transmission.Size 31.7mm/1.25"Apparent FOV 50°Eye relief 20mmWeight 168g (5.92oz)

​The BRESSER EQ-3 is a German equatorial telescope mount that can be used universally for light to medium-weight telescope tubes with a net weight of up to 5 kg.The only requirement for telescope tube mounting is a universal Vixen profile GP dovetail mounting bar - found on many commercially available telescope. This high-quality equatorial mount allows easy alignment to the celestial pole in no time and then allows tracking of all celestial objects manually with its single RA axis. Both RA and DEC axes come with manual slow motion control cables, for easy adjustment of your telescope's pointing.  Also included is a sturdy, yet lightweight, aluminium field tripod, which can be individually adjusted in leg height to give you perfect stability, even on rough ground. The included 1.5 kg counterweight is used to adjust the balance between the telescope tube and the mount.  Further counterweights can be supplied if needed. NOTE: If you want automatic Right Ascension tracking of celestial targets, this telescope mount can be equipped with the optional motor set Art. 4951400.FEATURESGerman equatorial telescope mountFor light to medium-weight telescope tubes of up to 5 kg net weightUniversal Vixen GP-style dovetail holderEasy polar alignment with adjustable altitude and azimuth axesAllows convenient tracking by slow motion right ascension axisWhat's IncludedBRESSER EQ-3 mountField tripodCounterweight 

With the usage of barlow lenses, you can extend the focal distance of telescopes and enhence the magnification of your observated deep sky objects. Thus, you can use the advantages of eyepieces with greater focal distance like the long eye relief as well as a more convenient insight at higher magnifications. Due to their 3-element air-spaced lens design with ED glass, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.FEATURESsuitable for observations and photographyincrease fivefold the focal distance3-element air-spaced lens design with ED glassfully multi-coated brass eyepiece clamping ringSCOPE OF DELIVERYBarlow lens (1pc)

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.Features: Suitable for visual observations and astrophotographyDoubling the effective total focal length of the telescopeFour lens telecentric design Fully multicoatedFilter thread for color or nebula filters

BRESSER 5mm 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.

The BRESSER 8-day 4CAST XL 7-in-1 Wi-Fi Weather Station with a solar-powered sensor features a modern design with a huge 48.3 cm (19”) wide-angle colour screen for displaying your meteorological data. Ideal for offices, schools and plant nurseries – the base station is perfect for providing an overview of the weather in large rooms. In addition to displaying the data from your outdoor sensor, the Wi-Fi weather station can also connect to the Internet to display forecast data from the ProWeatherLive platform, including an 8-day weather forecast with maximum/minimum temperatures and the chance of rain, as well as the local visibility and cloud cover. Solar-powered weather station The weather station comes with an eco-friendly 7-in-1 outdoor sensor that operates via solar power and measures the temperature, humidity, wind speed, wind direction, rainfall, UV level and light intensity. The sensor uses the sunlight as power-source. Simply align the large solar panel with the sun. In case the sun doesn't shine, 3 AA batteries (not included) serve as a backup. The data will then be displayed on your base station, which has a range of up to 150 metres. Wi-Fi weather station with feature-packed base station In addition to displaying the measurements from your outdoor sensor, the base station of the 8-day 4CAST XL Wi-Fi Weather Station also has many other functions. For example, it comes with a built-in thermo/hygro sensor which measures the ambient indoor temperature, humidity and air pressure. There is also a maximum/minimum memory – perfect for monitoring your indoor climate and preventing mildew and excessively dry air. The max/min values for outdoor, temperature, rainfall and other outdoor measurements can also be viewed on the display. In addition to weather data, the large screen has plenty of space for displaying the time, date, day of the week and moon phase. The sunrise/moonrise and sunset/moonset times are also displayed at the top of the screen. Share your weather data and connect to your smart home The readings from the wireless solar-powered sensor can be published on the Internet with a few simple clicks so that you can access your data remotely using the ProWeatherLive weather platform (with a web browser or the app). You can also send the measurements from your weather station to a smart home system free of charge using the German-language portal AWEKAS.
