Vixen NPL Eyepiece 40mm (1.25") Plössl

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

Who hasn't dreamed of a trip to the stars? The BRESSER Space Explorer MC 90/1250 automatic telescope will take you on an exciting journey into space. The telescope is easy to use, even for beginners - after aligning with one, two or three stars, you can choose an object from the 270,000 pre-installed celestial objects. Whether you want to observe a fascinating gas planet or a bright deep-sky object, the telescope will automatically move to your desired target. Thanks to the built-in motors in both axes of the azimuthal mount, the target object is automatically tracked so that you can sit back and enjoy the night sky. Explore the night sky with the Maksutov telescope Featuring a long focal length of 1250 mm, this telescope is ideal for making exciting discoveries in the solar system and beyond. Take a close look at the gas clouds on Jupiter, or watch the rings of Saturn through the telescope for the first time with your own eyes. Thanks to the 90 mm aperture, the telescope collects about 165 times more light than the human eye. However, it's not just the planets that look stunning through the high-quality optics. It's also worth venturing further afield into space: marvel at the sight of the Orion Nebula, 1,344 light years from Earth, or the famous Ring Nebula M57 in the constellation Lyra. The two included eyepieces with 25 mm and 12.5 mm focal lengths will show you these objects and many others at 50 or 100 times magnification. And because the best observation spots are usually not found in your immediate vicinity, the telescope features a compact Cassegrain design for easy transport. If there is a stable table at your observation site, you can even leave the tripod at home. Everything you need for exploring the night sky The telescope also allows you to capture images of the night sky. Simply attach the smartphone holder to the eyepiece, and take snapshots of planets, open star clusters and other night sky objects. The telescope is also ideal for observing and taking photos of the moon. In order to comfortably watch Earth's natural satellite through your Maksutov-Cassegrain telescope, it is best to use the included moon filter. The moon filter darkens the image slightly and increases the contrast to provide a more comfortable view. Perfect for exploring fascinating moon craters, lunar seas and shadows in the twilight zone! The telescope also comes with a star chart to help you navigate the night sky with its mythically named constellations. Discover the night sky with ease with the BRESSER Space Explorer MC 90/1250 automatic telescope - also ideal for beginners!

The SLV eyepieces with high-quality lanthanum glass provide remarkably clear and high-contrast images of the night sky right to the edge of the field of view. The lanthanum elements almost completely eliminate chromatic aberration, producing a colour-neutral image right up to the edges. The lenses are also fully multi-coated for high light transmission. The eyecup can be twisted up and down, making the eyepiece suitable for glasses wearers. The large exit pupil distance of 20 mm means that the eye does not become fatigued during longer periods of use, and the entire field of view can be seen clearly even when wearing glasses. The eyepiece also features a standard 1.25" filter thread for colour and nebula filters. In addition, the insides of the eyepiece sleeves are fully blackened to reduce distracting reflections.

​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.
