This complete telescope set for beginners contains everything you need for your new hobby: a refractor telescope with 80 mm aperture and 900 mm focal length, an equatorial mount, a tripod and a wide range of accessories for astronomical observations. The system is very easy to handle and can even be used by children. Simply unpack, set up and get started – you will be amazed at what you will discover! Easy start with user-friendly classic – the telescope The astronomical telescope is a traditional lens telescope, a so-called Fraunhofer achromatic refractor. The advantage of this established telescope type: even beginners and children find it easy to operate. In addition, the BRESSER Quasar scores points for its modern, precisely coated optics with good imaging properties. A direct comparison shows: With its 80 mm aperture, this telescope already collects 30 % more light than a 70 mm telescope and the resolving power is better as well. This means that you can already marvel at some of the details on Mars through the Quasar. In addition, 80 mm aperture and 900 mm focal length mean a large focal ratio (ratio of the aperture to the focal length) of about 1 to 11.3 (F/11.3). The result: a very sharp image with good contrast. Due to its long focal length the entry-level telescope is a specialist when it comes to observing the moon, sun, planets, open star clusters and globular clusters. But you can also take a look at many gas nebulae through this telescope, such as the famous Orion Nebula M42 or the Ring Nebula M57. How big will you see the fascinating celestial bodies? The 80 mm aperture achieves a resolving power that easily allows magnifications of up to about 160x with really sharp images. Technically, much more is possible, theoretically up to 675x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition to the equipment, the conditions play a role as well: the air turbulence in the atmosphere (seeing conditions) also determines how much you are able to magnify. Sturdy base for your easy astro-beginning – mount and tripod Found the perfect spot for your nocturnal explorations? Then install the telescope effortlessly on the height-adjustable aluminium tripod using the equatorial mount. The advantage of this type of mount: unlike the azimuthal models, you compensate for the movement of the celestial bodies along just one axis instead of two. To do this, you align one axis parallel to the Earth's axis, which is called "alignment". This is easily done by pointing it approximately to Polaris. The beginner's telescope also comes with two flexible shafts with a fine adjustment, which simplify the movement of the axes. They make adjusting and tracking very precise and comfortable. Handy storage: On a plate between the tripod legs, you can store your accessories within easy reach.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! The complete package for your sky observations – the accessories The extensive astronomy accessories including a safe solar filter enable you to immediately direct your gaze through the lens telescope to the sky – day and night. When observing at night, the LED viewfinder helps you find your way around: just install it parallel on the telescope, adjust it and use it to align and locate celestial objects. When you look through it, the red dot projected onto a ground-glass screen inside appears to hover in front of the sky. It shows you the spot to which the tube is pointing. This allows you to navigate easily before taking a closer look with the telescope's high magnification. Different perspectives of your astronomical discoveries are made possible by the two eyepieces, which enable different magnifications. With their sockets, which have a standard diameter of 1.25 inch (31.7 mm), they are simply inserted into the telescope's focuser. You want to see even more details? Then triple the magnification of the eyepieces with the 3x barlow lens. Always comfortable while observing the stars – for this purpose the 90-degree star diagonal mirror is included. That way you always enjoy a pleasant view into the telescope. Even if it is pointed upwards into the sky, you can comfortably look in from the side. Discover the beauty of our own star: Using the telescope in combination with the solar filter you can safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Have you always been fascinated by astrophotography? Then your smartphone camera and the smartphone adapter will get you started. This way you'll quickly enjoy your first own photos e. g. of the moon or the sun.

The BRESSER TRM-301 is a trinocular biological microscope of first-class quality: This means excellent imaging, good ergonomy, high stability and a modern attractive design. It is a laboratory microscope, which permits an intensive use, e.g. in medicine, biology, agriculture and industry area. Also, we can recommend it to the engaged hobbyist as his "microscope for a lifetime". A particular important feature of the TRM-301 is its ability for the Köhler illumination. This optimal illumination is bright, cool (going easy on the object), homogenous, reflex free and rich in contrast, so it makes the full use of the microscope optics. The Köhler illumination is standard for scientific research and microphotography. It is achieved with the fixed field diaphragm and the adjustable Abbe condenser (numerical aperture 1.25; with iris diaphragm). Naturally, the TRM-301 has the other features, which are typical for high-quality microscopes: lengthwise and cross moveable stage, ergonomic coaxial focusing knobs (fine focus: 200 µm / full turn), continous dimmer, planachromatic objectives (4x, 10x, 40x, 100x-oil retractable), 10x wide field eyepieces (mounted in 30° inclined eyepiece tubes), adjustment of eye relief, diopter adjustment and the phototube.
