BRESSER Erecting Lens 1.5x (1.25")

BRESSER 40mm Plössl Eyepiece 1,25" (31,7mm) Since years a well known and approved Plössl eyepiece. Ideal to improve the performance of your telescopes for a low budget price. All the BRESSER Plössl eyepieces provide sharp and high-contrast images because of the 4-lens design. All lenses have fully-multicoated surfaces which prevents reflections efficiently. Every eyepiece is equipped with a foldable rubber eyecup to avoid straylight from the sides and the inner eyepiece shaft is carefully blackened as well. Housing and eyepiece shaft are completely made from metal - no plastic is used. Filter thread for use with colour- and nebular filters is also available. All these Plössl eyepieces offer a much better image quality than all the very simple made Kellner and Huygens eyepieces. FEATURES Focal length: 40 mm Field of view: 46° Lens-Design: 4 lenses in 2 groups , fully-multicoated Housing material: completely made from metal Rubber eyecup: YES, foldable Filter thread: YES Storage: Twist-pack SCOPE OF DELIVERY BRESSER Plössl eyepiece with rubber eyecup Twist-pack

Set off on your personal journey to the stars with the BRESSER Sirius 70/900 AZ lens telescope. The complete astronomy set already includes everything you need to start observing the sky: the astronomical lens telescope with 70 mm aperture and 900 mm focal length, the azimuthal mount, the tripod and a wide range of accessories for fascinating discoveries. At the same time, it is very easy to operate - ideal to amaze even children with a view of the night sky. Simply a stargazing classic - the telescope With this lens telescope - a so-called Fraunhofer achromatic refractor - even total astro-beginners and children can easily explore the secrets of our night sky. Because this classic design impresses with its special user-friendliness and easy handling. To ensure that you enjoy good imaging properties when looking at the Moon, Sun, planets and star clusters, the entry-level telescope has been equipped with modern, precisely coated optics. The 70 mm aperture collects a total of 100 times more light than the human eye. And it is also convincing compared to a comparable 60 mm telescope: the light gathering capacity is 36 % higher and the resolving power is also better. Thus, with the 70 mm lens telescope, significantly more details are visible at the same magnification, e.g. on Saturn's rings or the two main cloud bands of Jupiter. But how big do the celestial objects appear then? The resolution of the 70 mm lens lets you enjoy really sharp images at magnifications up to about 140x. For comparison: with a 60 mm aperture, this is only possible up to 120x. Technically, of course, the starter telescope can do even more - theoretically up to 675x with the included accessories. However, with increasing magnification, the image can slowly become more and more blurred. And how big you can really see the planets, star clusters and co. depends not only on the telescope. Another important factor: the air turbulence in the atmosphere (seeing conditions). A sharp image with good contrast - this is what the starter telescope achieves with its large focal ratio of about 1 to 12.9 (F/12.9), which is calculated from the ratio of the 70 mm aperture to the 900 mm focal length. And you will see: Due to the long focal length, especially the Sun, Moon, planets, open star clusters and globular clusters become absolute eye-catchers. Solid base for your stargazing hours - mount and tripod Found the ideal location for your nocturnal explorations? Then attach the telescope tube to the height-adjustable aluminium tripod with azimuthal mount. And this azimuthal mount is particularly compelling due to one quality: operation is really child's play. Simply swing the telescope by hand to the left or right, up or down, as with a common photo tripod. This way you can quickly move your gaze from one celestial highlight to the next. And where are the accessories? Simply place them on the storage plate between the tripod legs. This way, eyepieces, solar filter and co. stay always within reach. All the trimmings - the accessories The beginner’s telescope comes with everything you need for a quick start in stargazing. When searching for celestial bodies worth seeing, take your first look through the included LED viewfinder. Because the direction finder helps you to align the telescope precisely and find astronomical objects. It works like this: The LED finder is mounted in parallel on the telescope tube. It projects a red dot onto a small ground-glass screen that appears to float in front of the sky when you look through it. And that is exactly where the aperture of your telescope points. This way, you can always keep an overview of the night sky - before focusing your attention on the details through the magnification of the telescope. And you decide how high this magnification is by choosing the eyepiece. You will be amazed: the two eyepieces included in the set (4 mm, 20 mm) allow you to admire completely different images of the same object. If you one day want a change of perspective, you can expand your astronomy set with a large selection of eyepieces. For this purpose, the socket diameter is 1.25 inches (31.7 mm), which corresponds to an international, manufacturer-independent standard. You like what you see, but would love more detail? Then simply insert the 3x Barlow lens between the telescope and the eyepiece. And you have tripled the magnification of the eyepiece! Observation comfort and a pleasant view - this is what the 90-degree star diagonal mirror is made for. Even if your starter telescope is pointed vertically into the sky, you don't need to lie down underneath it to see anything. Instead, simply look in comfortably from the side and enjoy the view. But it's not only at night that we should look skywards. For only during the day you can see a very special star: our Sun. So put the solar filter in front of the lens and safely look at sunspots and granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! Would you like to share your discoveries with friends and family? Then take your first steps in astrophotography right away - and those are done in no time with the smartphone camera adapter for your beginner's telescope. The Moon, Sun, planets, open star clusters and globular clusters always make a good picture. Discover what our night sky has to offer with the BRESSER Sirius 70/900 AZ refracting telescope.

Filter Set 3 is recommended for Moon & Planets from 150mm (6") Aperture Set 3 includes the following filters: Explore Scientific Filter 1.25" Light Blue No.82A - 0310265 The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. Explore Scientific Filter 1.25" Violet No.47 - 0310272 The purple filter is perfect for watching Venus. Seeing through it, the dark clouds of the Venus atmosphere become even better visible. He also clears up the structures of the rings around Saturn. Using big openings and having a clear sight this filter is also good for watching Merkur. Explore Scientific Filter 1.25" Light Red No.23A - 0310271 The blue/blue green light is totally blocked. The contrast between the card and the lighter zones will enormously increase. This is truly helpful when you watch Jupiter or Saturn. Or for mars, watching the poles. Explore Scientific Filter 1.25" Yellow-Green No.11 - 0310269 Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details. FEATURES Made from high-quality optical glass Filter glass is absolutely parallel All optical surfaces have anti reflex coatings Filter housing from black anodized aluminum Filter threads on both ends (female/male) Multiple filters usage is possible SCOPE OF DELIVERY 4pcs color filter 4pcs protection-case
