Vixen Flattener HD Kit für FL55SS Telescopes

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. FEATURES Objective lenses: 55 mm fluorite Focal length: 300 mm F5.5 Resolution and limiting magnitude: 2.11, 10.5 Light-gathering power: 62x Dimensions and weight: 80 x 282 mm; 1.5 kg Adapter and connections: 31.7 mm receptacle, 60 mm thread WHAT’S INCLUDED 55 mm optical tube with fluorite APO Dovetail adapter Extension Tube 60 mmDew cap Dust covers

Convert your FL55SS fluorite refractor into a high-performance astrograph The kit includes a high-performance reducer, flattener and the ''EX TUBE 66'' extension tube, which was developed for the FL55SS Fluorite Apo Refractor and improves the photographic performance by flattening the image right up to the edges. Ultra-sharp image over the entire field of view of the DSLR full-frame sensor Designed for prime-focus photography with the FL55SS, the Flattener HD flattens the entire field of view of full-frame DSLR cameras. The 44 mm image circle covers the entire field of view of a full-frame DSLR camera. When used in combination with the HD5.5 Reducer, the focal length is reduced by 0.79x (from f5.5 to f4.3) and the illuminated area retains a diameter of 44 mm, which significantly improves the sharpness across the entire field of view of the DSLR camera. 96% illumination to the edges of the field of view The Flattener HD was specially developed for the FL55SS refractor in order to reduce light loss to a minimum. The field of view is fully illuminated up to the edges. Exceptionally high contrast The same anti-reflective AS coatings used on our high-end VSD 100 f/3.8 astrograph are also used here to provide an outstanding light transmission of 99.9% per lens surface. In addition, the matte black surface of the Reducer HD kit eliminates loss of light, ghosting and scattered light. FEATURES Ultra-sharp image over the entire field of view Reduces the focal length and flattens the image Very high light transmission (approx. 96%) AS coatings with 99.9% light transmission per lens surface Also suitable for full-frame DSLR cameras Includes 66 mm extension Reduces the aperture ratio to f4.3 Distance to chip: 63.5 mm Dimensions: 58mm x 30mm / 68mm x 45.3mm Weight: 107g / 237g DELIVERY CONTENT Reducer HD Flattener HD Extension tube Dust caps

Focal Reducer for the SDP65SS AstrographDeveloped exclusively for the SDP65SS, this focal reducer shortens the focal length by a factor of 0.8× and lowers the focal ratio from f/5.5 to f/4.4. In practice, the focal length is reduced from 360 mm to 288 mm, enabling a much wider field of view.The advanced optical design uses 2 elements in 2 groups with a multi-coating for high light transmission.  The reducer illuminates a 30 mm image circle, covering the APS-C format at over 90 % right into the corners. Even at the extreme edge of a 44 mm full-frame sensor, it maintains ≈ 70 % light intensity while keeping distortion low—for sharp, clean star images across the frame. FEATURES Focal length: SDP65SS 360 mm (f/5.5) → 288 mm (f/4.4) Optical design: 2 groups / 2 elements Coating: Multi-coating Connection (telescope side): M48 × 0.75, internal thread Connection (camera side): M56 × 0.75, internal thread Filter thread: M48 Illuminated image circle: 30 mm (APS-C > 90 %, full-frame edge ≈ 70 %) SCOPE OF DELIVERY SDP Focal Reducer 0.8×

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation. The BRESSER Messier 6 inch Planetary Dobson is something very special. Despite its low price, it offers a variety of functions and quality, which you sometimes look for in the considerably more expensive devices in vain. With an aperture diameter of 150 mm and a focal length of 1200 mm of this high quality BRESSER newtonian optics, the observation of the moon, the planets and planetary nebulae is particularly well possible.  Craters and grooves of the moon as well as the fast changing shadows cast by the so-called terminator line are exciting observation targets. Saturn with its impressive ring, Jupiter with its bands of clouds and the movement of its easily visible moons, the crescent shape of Venus and the glowing red Mars are good examples of what this telescope can be used for. Because of the long basic focal length you can easily achieve the high magnifications required for this purpose with this telescope. You do not need expensive special eyepieces. In short, this is a telescope primarily for detailed observation. Nevertheless bright deep sky objects like the Orion Nebula or the galaxies Messier 81 and 82 etc. can be observed as well. Also photography is no problem with this tube. Here is another strength of this telescope: if you want to take pictures, you can simply unscrew the altitude wheels from the tube and put them on a EQ mount with an optionally available dovetail rail - and nothing more stands in the way of astrophotography. The included eyepiece adapter has the common T2 connection thread (M42x0.75mm), to which almost every standard camera can be attached. Only the camera specific T2 adapter ring is additionally required. Of course, also common USB planetary cameras with 1.25 inch or 2 inch plug diameter can be used directly with this telescope. With the original equipment you can observe immediately - an optical 6x30 viewfinder and a 25 mm SPL eyepiece are included. For those who want to transport the device as compact as possible, the new 6'' BRESSER Messier Planet Dobson makes it very easy - the rocker box can be disassembled in a few easy steps, because the parts are assembled with metal quick connectors. So a bulky rocker box quickly turns into a handy flat package of boards. A telescope whose versatility, performance and user-friendliness set new standards in this price class. Please note that Newtonian reflector telescopes are very good for astronomical observations of the starry sky, but are not well suited for observing nature and landscapes during the day. For nature and landscape observations we therefore recommend BRESSER lens telescopes.
