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.

In the northern hemisphere*, simply position the polar star and two additional stars in the finder’s field of view so that each star is aligned with the corresponding positions in the finder reticle. This enables you to easily configure the equatorial mount with an accuracy of 3 arc minutes or less. The new design of the polar scope eyepiece improves the visibility of stars and makes the scale easier to read. *Three stars for polar orientation in the southern hemisphere are located in Octans. What is the polar alignment scope? The polar alignment scope is a small telescope that is installed parallel to the R.A. axis of an equatorial mount such that it matches the R.A. axis to be parallel in the direction of the diurnal motion of stars. The polar alignment scope utilizes 3 stars (Polaris, Delta UMi and 51 Cep) near the north celestial pole. To locate the north celestial pole, simply align the positions on the reticle in the polar alignment scope with the 3 designated stars. In addition, the patterns of the Big Dipper and Cassiopeia are engraved on the polar alignment reticle for use as a guide for the north celestial pole. The polar alignment scope can align the polar axis of the equatorial mount as accurately as 3 arc minutes or less. The marks and patterns on the built-in reticle provide everything that you need for polar alignment The necessary information for polar alignment is integrated into the reticle, which is designed for locating the north (or south) celestial pole. It is not necessary to configure an hour angle setting in the dark. This makes polar alignment easier, as you can look through the eyepiece of the polar alignment scope. A free app is available to download via the following link. https://www.vixen.co.jp/app/ Dark field illumination (with automatic power off function) The switch on the polar alignment scope’s brightness adjustment dial illuminates the reticle in red when activated. Compared with bright field illumination, this prevents less bright stars from disappearing from the scope's field of view. The brightness can be adjusted in 8 levels by turning the brightness adjustment dial. The red light dims gradually after a certain period of time and turns off automatically. Easy to set up Remove the mounting block on the front side and the cap on the rear side of the POLARIE. Then insert the POLARIE PF-L finder scope into the POLARIE to complete the installation. The telescope is ready for use in no time! FEATURES Easy alignment via reference stars Dimmable red light No date or time settings required Light switches off automatically Free app from https://www.vixen.co.jp/app/ DELIVERY CONTENT 1x PF-L II polar finder 1x CR2032 battery
