BRESSER Topas 8-24x50 Binoculars

An amici prism allows for a comfortable 90° viewing position and creates an erect image without left-right reversal. This makes it especially suitable for nature observations but it can also be very helpful with astronomical observations. Particularly beginners may find it easier to orientate in the sky when they compare the view through the telescope with what they can see with their naked eyes.With this  amici prism an astronomical telescope can be used as a powerful spotting scope.Suitable for refractor telescopes as well as Maksutov-Cassegrain style telescopes with 1,25" visual back.FEATUREScomfortable eye relief for refractor telescopes90°- viewing position and image without left-right reversalastronomical telescope turns to a powerful spotting scope1,25" visual backfully multicoated prismSCOPE OF DELIVERYAmici Prism 90° 31.7mm/1.25"

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. With the included smartphone camera adapter you can take pictures of your observations right through the telescope's eyepiece. Moon, planets, stars – the BRESSER Polaris-II 102/600 EQ3 lens telescope takes beginners a lot closer to the beauties of the universe. The complete set comes with everything you need to admire the night sky: the astronomical lens telescope with 102 mm aperture and 600 mm focal length, the equatorial mount, the tripod and a wide range of accessories for exciting astronomical observations. Explore the fascinating surface of the moon and marvel at the sight of the planets. But you can go even further than that, because the entry-level telescope also shows you star clusters and gas nebulae in the deep sky range. Operation is very easy – so you are off to a successful start in astronomy in no time. Getting started in astronomy with a classic – the telescope Effortless handling, impressive images: As an easy-to-use Fraunhofer-type achromatic refractor, this classic lens telescope is the perfect first telescope for beginners and children. Thanks to its modern, precisely coated optics, it offers good imaging properties as well. The 102 mm aperture already collects a lot of light from the celestial objects. In addition, 102 mm aperture and 600 mm focal length result in an average focal ratio (ratio of aperture to focal length) of about 1 to 6 (F/6). Because of this average focal ratio the beginner’s telescope is an all-rounder for all celestial objects. So observe interesting details on the moon and planets with high magnifications. Or choose a medium to low magnification and admire the sight of open star clusters such as the Pleiades, globular clusters like M13 or gas nebulae like the Orion Nebula M42. Speaking of magnifications: How big will the celestial objects appear through this telescope for beginners? The aperture of 102 mm achieves a resolving power that easily allows magnifications of up to about 200x with sharp images. Technically, the telescope can do more. However, with increasing magnification, the images can become blurred. And the telescope is not the only factor determining the possible degree of magnification. The air turbulence in the atmosphere (seeing conditions) also plays a major role. Solid base for your celestial exploration – mount and tripod Found the perfect observation site? Then set up the telescope on the height-adjustable aluminium tripod with equatorial mount. The advantage of equatorial mounts: Unlike with an azimuthal mount, you don’t have to move both axes at the same time. Instead, one axis is simply aligned parallel to the Earth's axis at the beginning. In this so-called alignment, you point the axis in the direction of the polar star. After that, you can track the celestial bodies just on this one axis. Another benefit of this mount: you move the axes via two flexible shafts with fine adjustment. Perfect for delicate as well as comfortable adjustment and tracking of the entry-level telescope. To ensure that your accessories are always within reach during fascinating discoveries, there is an extra storage plate between the tripod legs.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything for your first steps in stargazing – the accessories The astronomy set contains lots of accessories so that you can immediately set off on your discovery tour of the night sky. Use the LED finder to precisely align your beginner's telescope and thus find celestial objects more easily. You just have to install the direction finder in parallel on your telescope. It projects a red dot onto a small ground-glass screen that appears to be floating in front of the sky when you look through. Since the aperture of your telescope points in the exact same direction, this helps you to keep track of the night sky. Two eyepieces (K-20mm, K-4mm) are included so that you can admire celestial bodies in two different magnifications. Still not enough for you? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. And should you ever wish to change perspective during your astronomical observations, the standard tube diameter of 31.7 mm (1.25 inch) gives you a wide choice of additionally available eyepieces. The 90-degree star diagonal mirror, on the other hand, provides more convenience and a comfortable view. Even if your entry-level telescope is pointed vertically upwards, you can simply look in from the side.
