Vixen extender PH set for R200ss

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.FEATURES: Suitable for visual observations and astrophotographyDoubling the effective total focal length of the telescopeFour lens telecentric design Fully multicoatedFilter thread for color or nebula filtersSCOPE OF DELIVERY: Fokal Extender 2 x Adapter 2" (50,8mm) auf 1,25" (31,7mm)

The Vixen corrector PH is a 3-element Wynne corrector for demanding applications. Designed for the Vixen R200SS Newtonian reflector, but also suitable for other optics with similar specifications.The optical design consists of 3 lenses in 3 groups. The corrector provides excellent correction of system-induced coma of parabolic mirrors and the resulting spherical aberration. The corrected field has a diameter of 44 mm, making it suitable for the 24x36 mm format (full-frame DSLR/CCD cameras). This guarantees razor-shape images across the entire field. The lens surfaces are coated with a cutting-edge 99.9% anti-reflective AS coating, which is also used for Vixen's flagship VSD100F3.8.Turn your Vixen R200SS reflector telescope into the perfect astrograph!FEATURESPremium coma corrector for the R 200SS Newton refelctor 3 lens systems in 3 groups, guarantees absolute colour purity and sharp stars to the edge of the field of viewImage illumination up to 44 mm for full-frame imagesReduces the focal length of the R 200SS from 800 mm to 760 mm 1:3.8Also suitable for visual observations with an eyepiece adapterWeight: 175 gDELIVERY CONTENTComa correctorDust caps on front and back

Explore hidden worlds through your own eyes – with the BRESSER Pollux-I telescope starter set for budding amateur astronomers, you can go on your own journey of discovery in outer space. Everything you need is already included: the astronomical reflector telescope with 150 mm aperture and 750 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Perfect for getting started quickly: the system is very easy to use. In addition, the entry-level telescope impresses with its versatility: you can observe the Moon and planets as well as star clusters, gas nebulae and even galaxies through the high-quality optics. Due to the parabolic primary mirror the image delights with impressive sharpness and high contrast. In addition, the 2-inch focuser allows for the use of high-quality eyepieces. Perfect conditions for fascinating sights of the night sky! Time-proven optics for your first astro-steps – the telescope By choosing the Pollux-I, you’ll start your journey to the stars with a classic Newtonian reflector telescope. Beginners are often surprised by the fact that with telescopes of this type you don't look in at the back of the tube, but at the front and laterally. This gives you the advantage of always being able to look into the telescope in a comfortable posture, even when it's pointed vertically upwards at the sky. In addition, these reflector telescopes offer optics that are absolutely free of chromatic aberrations and thus provide good imaging properties. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 750 mm focal length result in a short focal ratio (ratio of aperture to focal length) of 1 to 5 (F/5). On the one hand, this makes the telescope fast and provide a bright image. On the other hand, high magnifications can be achieved. This combination makes the entry-level telescope so versatile. In addition, the Pollux-I is equipped with a parabolic primary mirror. The remarkable effect of this special mirror shape: you enjoy excellent imaging properties at all magnification levels. So you can look forward to the complete range of celestial highlights. At low to medium magnification, you can admire deep-sky objects such as open star clusters, globular clusters, gas nebulae and even galaxies such as the pair of galaxies M65 and M66 in the constellation Leo. And at high magnifications, observing the planets or details on the Moon is an absolute pleasure. You can get really close to your favourite objects: The aperture of 150 mm achieves a resolving power that allows magnifications of up to about 300x with sharp images. Technically, even higher magnifications are possible, theoretically up to 562.5x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition, the prevailing conditions always make a difference: How highly you can magnify always depends not only on the power of the telescope but also on the air turbulence in the atmosphere (seeing conditions). The telescope also impresses with its flexibility in terms of eyepiece compatibility: it comes with a 2-inch focuser (focuser extension) and an adapter from 2 inch to 1.25 inch. This enables you to use eyepieces with 1.25-inch sockets (about 31.7 mm) as well as eyepieces with the larger 2-inch sockets (about 50.8 mm) with large fields of view. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-I reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Perfect foundation for fascinating discoveries – mount and tripod Your beginner's telescope is securely held by the height-adjustable aluminium tripod with equatorial mount. The special feature of this mount, also known as a parallactic mount: in contrast to azimuthal models, the movement of the celestial bodies is only compensated for on one axis instead of two. For this purpose, you simply align one axis parallel to the Earth's axis by pointing it approximately at Polaris. For precise and comfortable alignment and tracking of the entry-level telescope, the Pollux-I comes equipped with two flexible shafts with fine adjustment. And to ensure that the interchangeable eyepieces, barlow lens etc. always remain within reach, they can be stored on the tray 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! Well equipped for the ideal start – the accessories Your entry-level telescope comes with a wide range of astronomy accessories so that you can start to be amazed right away. For example, the LED viewfinder helps you align the telescope and find celestial objects. Installed in parallel on the telescope, this direction finder shows you a red dot when you look through it. It appears to hover in front of the sky and thereby shows you where the telescope is pointing. Varying view of the sky: With the two eyepieces with 1.25-inch sockets (31.7 mm), you can admire your astronomical discoveries at different magnifications. The 3x barlow lens already included in the set triples the magnification of the eyepiece you are using. Enjoy safe observations of our Sun with the included solar filter. This way you can easily take a closer look at sunspots and granulation on our own star. CAUTION: Never point the telescope at the Sun without the solar filter! Astrophotography for beginners: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. This way you will quickly impress friends and relatives with your own first snapshots e. g. of the Moon or the Sun.
