Vixen SD115S apochromatic Refractor

This telescope set has everything that you need for hobby astronomy. It includes a telescope, a mount with automatic tracking, a tripod and eyepieces. Featuring the STARBOOK TEN control system, the telescope locates celestial objects automatically so that you don’t need to search for them manually. Even if you’re not an expert, you can still give your friends an exciting tour through the night sky! The SXD 2 mount in detail With a combination of the best features from the Sphinx series and the all-new STAR BOOK TEN manual control, Vixen has developed a new generation of SX mounts for demanding observers and astrophotographers. The SXD2 mount comes with the new STAR BOOK TEN control and can be operated manually or with a computer. Featuring the same precision stepper motors as the top-of-the range AXD mount, the SXD2 sets a new standard for performance in the Vixen mount range. Compared with the SX mounts, the SXD2 has a quieter tracking system, and the increased precision of the motors provides better performance for the long exposure times used in astrophography. Precision stepper motors and micro-step motion control system The star feature of the SXD2 is the precision stepper motors, which offer better performance and responsiveness than previous models. The micro-step motion control system has powerful yet very quiet drive characteristics that offer both fine control and quick swivel movements. Built-in bearings The bearings of the RA and DEC axles and the worm shafts were significantly improved in order to reduce the load on the motors. The motors are much quieter than those on previous models. Robust RA and DEC axles High-precision and thick steel shafts in RA and DEC increase the robustness of the SXD2 mount. High-precision worm gears High-precision processing technologies were used to rectify problems with the worm gear. The edges of both worms and worm gears are particularly smooth, which enables them to deliver very high precision. Declination axis functions as counterweight The sturdy motor units are located in the lower section of the declination axis to ensure that the SDX2’s centre of gravity is below the intersection of the RA and DEC axis. As a result, fewer additional counterweights are required. The SD115S in detail The ED81SII, ED103S and ED115S refractors were originally designed for visual observers or photographers with an APS-C camera. The new SD series features new inner panels which are optimised for full-frame cameras and illuminates images with a frame size of 44 mm. The SD 115 ED refractor is the largest refractor in the Vixen range. Thanks to the FPL-53 lens, it offers an extremely high contrast and sharpness. This type of lens produces true colour and high-contrast images. Another advantage of the SD refractors is their very short length and lightweight design.

High-performance flattener and reducer set connection rings for Vixen telescopes SD81S, SD103S and SD115S, as well as the ED predecessor series. High-performance flattener and reducer set The kit consists of a high-performance flattener, a reducer for reducing the focal length, and connection rings (distance ring SD81, EX Tube 66), which were developed for prime-focus astrophotography with the SD81S, SD103S and SD115S telescopes. The flattener and the 0.79x reducer deliver a significant increase in telescope performance and image quality. You obtain a flat and sharp image until the edges, including with a full-frame DSLR camera. Ultra-sharp image over the entire field of view of the DSLR full-frame sensor The SD flattener improves the image quality to the edge of the field of view without changing the original focal length of the telescope. The field of view of the DSLR camera with a full-frame sensor is fully illuminated (44 mm), ensuring that stars appear sharp until the edges of the image. When used in conjunction with the Reducer HD, the focal length is reduced by a factor of 0.79 (f/7.7→6.1) whilst maintaining the 44 mm illumination. High-contrast AS coating The anti-reflex AS coating, which is also used on our high-end VSD 100 f/3.8 astrograph, delivers a high light transmission of 99.9% per lens surface. Loss of light, ghosting and scattered light images are virtually eliminated thanks to the completely matte interior coating. FEATURES Reduces the focal length by a factor of 0.79 Designed for full-frame cameras High-contrast AS coating Ultra-sharp image over the entire field of view Designed for full-frame DSLR cameras Illumination: 44 mm Correct distance to chip: 63.5 mm Designed for the SD81S, SD103S and SD115S Also suitable for the ED81S, ED103S and ED 115S DELIVERY CONTENT SD Flattener HD Reducer HD Adapter ring for SD81 66 mm EX extension tube Dust caps

High-performance, top-of-the-range fluorite apochromat for mobile astrophotography and observers. Thanks to its small size and lightweight design, this high-quality fluorite refractor is ideal for excursions and air travel. It displays razor sharp and bright stars across the entire field of view of the full-frame image sensor (95% illumination with 44 mm image circle). The FL55SSS turns into a fast F/4.3 astrograph with the optional flattener and focal reducer. It allows you to use extremely short exposure times and a provides a large field of view for large nebulae or comets.Note: To achieve the optimum image quality of the FL55ss, we strongly recommend the purchase of this reducer and flattener set.Despite the small aperture, the FL55SS features a high-resolution HR eyepiece that produces stunningly clear images of the moon and the bright planets. When used for astrophotography, it delivers razor-sharp images of stars that are guaranteed to impress.

The Vixen SD115IIS is a new 115 mm apochromatic refractor with high-performance Super-ED glass (= SD). The advantage of this SD refractor is its short length and low weight. The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material, reduces chromatic aberration across all colours.The new Vixen SD115SII no longer uses spacer plates, which leads to a significantly better image quality, especially with bright stars. In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates. In addition, you will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp as well as with extremely high contrast. Also look at the ring planet Saturn or the cloud bands on Jupiter. But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed in impressive detail.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, this refractor allows illumination with a 44 mm image circle for full format SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60 mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included folding mirror allows comfortable observation even in unfavourable observation situations and additionally offers a T2 thread for connecting a DSLR camera. This allows you to observe in straight line or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure grip when transporting the telescope. FEATURESObjective lens: D=115 mm, multi-coated 2-lens SD apochromat without spacer plates No more spikes on the stars Focal length: 890 mm (f7.7) Resolution and limiting magnitude: 1.01 arcseconds; 12.5 Light gathering power: approx. 270x more than the human eye Dimensions and weight: 125 mm dia x 920 mm; 6.3 kg Viewfinder telescope: 7x50 illuminated Adapters and connections: 60 mm thread, 50.8 mm and 31.7 mm socket, thread for T-ring Connection: 50.8 mm and 31.7 mm socket with flip mirror / folding mirror Photography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor SD115SII Telescope (OTA) Tube clamp with dovetail Dew cap Flip-Mirror / folding mirror Carrying handle Dovetail rail 7x50 viewfinder
