BRESSER Sewing Magnifier 2x/4x with LED Illumination, Diameter 120 mm

Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.

From the moon to Mars and beyond – NASA is reaching ever farther into space with its missions and space telescopes. Perhaps you’re interested in looking beyond our terrestrial horizons too? If so, you can take your first steps in the footsteps of famous astronauts and space explorers with this ISA Space Exploration NASA-themed 60/700 AZ Refracting Telescope. The complete astro kit comes with everything you need for your very own exploration of the night sky – a refracting telescope, an altazimuth mount, a height-adjustable tripod and plenty of astronomy accessories. The perfect way to get started: this astronomical telescope is extremely easy to use. Just open up the case, set your telescope up and start observing the stars! Explore the moon, planets and space yourself Start your journey to the stars in our own solar system. Our very own natural satellite – the moon – is always worth exploring through the 60 mm aperture and 700 mm focal length. The large aperture ratio of approx. 1 to 11.7 (F/11.7) guarantees high-contrast images. The two main bands of cloud of Jupiter and the rings of Saturn will also be clearly visible through the state-of-the-art, carefully coated lens, which has outstanding imaging properties. If you’re eager to explore even deeper into the unknown, your refractor telescope will give you a glimpse of globular clusters and open star clusters, such as the famous Pleiades. An entry-level telescope to help you get started If you’re keen to start your discovery, you have no time to lose! With this refracting telescope, you’ll be up and running in no time at all, even if you’re just a beginner. The user-friendly altazimuth mount on the stable tripod allows you to move quickly from one celestial object to the next with your telescope. As with a standard camera tripod, you simply pivot the telescope up and down, left and right with your hand. Use the 5x24 finder scope, mounted parallel to the tube, to quickly align the lens and seek out astronomical highlights for your observations. With low 5x magnification and integrated crosshairs, you can ensure that you have a clear picture of the night sky before focusing in on the detail with your telescope. Telescope with plenty of accessories – everything you need for stargazing With the right equipment by your side, your astro hobby can be even more fun. That’s why the sturdy hard case comes packed with plenty of useful accessories for safe transport. With three eyepieces, you can vary the magnification to give you a different perspective on our universe over and over again, while the 90 degree zenith mirror ensures a comfortable observation position at all times. Even if the lens is pointing vertically upwards, you can still observe comfortably from the side. Never lost in space – with the compass and star chart, you’ll always know exactly where to look. Plus, as our own planet has plenty to admire too, you can use your telescope with the reverse lens to observe animals and the nature around you during the day. Follow your role models at NASA and start your very own astro adventure with the ISA Space Exploration NASA-themed 60/700 AZ Refracting Telescope.

Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. 3-lens apochromatic telescope with FPL-51 glass, 130mm aperture and 910mm focal length - excellent image quality for H-Alpha solar observation and also for observing the starry sky at night. With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B3400 blocking filter. Solar observing in H-alpha: The LS130MT/B3400 is a complete telescope for observing the sun in H-alpha light, with 130mm free aperture (no central obstruction) and 910mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance. Fine adjustment is achieved with a solid 2 inch R&P focuser with 10:1 reduction. Blocking-filter is the B3400. The B3400 is good for solar imaging by cameras with very large sensor chips, and can also be used for visual observing. The B3400 blocking-filter is fix installed inside the 2 inch R&P focuser. Observing the starry night sky: The H-Alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. Then the 3-lens apochromatic refractor can be used as a normal telescope with 130mm aperture and 910mm focal length for observation and photography of the night sky. The FPL-51 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the R&P focuser of the telescope. Please note that the optionally available conversion kit 0551696 is absolutely necessary for the LS130MT version with B3400 blocking filter if the telescope is also to be used at night. The conversion kit is not required for the versions with B1200 and B1800. More applications: With additionally available accessories the LS130MT offers even more possibilities! - Double-Stack The LS130MT telescope can optionally be upgraded with the additionally available double-stack module LS130MT/DSII (item number 0551690). The DSII system is a internal double-stack module with Pressure-Tuner. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible. - Solar observing in White-Light If the H-alpha unit has been removed, of course either a sun filter can be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light. - Solar observing in Ca-K wavelengthThe additionally available "LUNT Ca-K Filter Module for LS130MT" (item number 0551697) can be used on the LS130MT to observe and photograph super-granulation and other effects visible at this wavelength on the sun. This makes the LS130MT a completely universal usable apochromatic telescope of highest quality! FEATURES 3-lens APO refractor, FPL-51 Aperture: 130mm (no central obstruction) Focal length: 910mm Bandwidth: internal Etalon with <0.7 Angstrom Tuning: air pressure tuning system Pressure-Tuner Blocking filter: B3400 with 2 inch connection Focuser: R&P with 10:1 reduction Two tube-ring with handle Sol-Searcher installed inside handle Dovetail bar at GP-level for astronomical mounts Weight: 12.1kg Length with dew-shield: 95cm Length removed dew-shield: 80cm SCOPE OF DELIVERY LS130MT Multipurpose Telescope Pressure-TunerB3400 blocking filter installed inside focuserTube extension for using without H-alpha Etalon 2 inch R&P focuser with 10:1 reduction Tube rings with dovetail bar Transport case (92 x 42 x 35 cm) Instruction manual
