Product information "Vixen Flattener HD Kit für FL55SS Telescopes"
Converts the FL55SS into a high-performance astrograph The kit consists of a high-performance flattener lens, a reducer and the EX TUBE 66 connection ring, which was developed for the FL55SS Fluorite Apochromatic Refractor and improves photographic performance by dramatically flattening the surface.

Ultra-sharp image over the entire field of view of the DSLR full-frame sensor
The Flattener HD for the FL55SS reduces the change in the focal length of the FL55SS to a minimum and improves the evenness of the surface for prime-focus photography. 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 image circle retains a diameter of 44 mm, which significantly improves the sharpness across the entire field of view of DSLR cameras with a full-frame sensor.

96% light volume to the edge of the field of view
The Flattener HD was specially developed for the FL55SS refractor to reduce loss of light to a minimum across the entire 44 mm image circle of full-frame DSLR cameras.

Exceptionally high contrast
The same anti-reflective AS coatings used on our high-end VSD 100 f/3.8 astrograph are used to provide an outstanding light transmission of 99.9% per lens surface. Thanks to the matte black surface of the Reducer HD kit, loss of light, ghosting and scattered light and largely prevented.

Vixen 60DA Focal adaptor for Canon EOS Cameras
Vixen 60DX Focal adaptor for Canon EOS Cameras This Vixen 60DX is a photographic adaptor for Canon EOS cameras, for use with telescopes with a 60 mm focuser drawtube connection thread. A redesign by Vixen uses new tougher materials for a more solid connection and also offers an accurate, well-machined camera rotator ring, in order to help frame your images perfectly. Camera-Adaptor for Canon EOS with 60mm Focuser connection thread Large inner diameter for full-format cameras, helping to minimise vignetting 6 locking 60° spaced bolts to hold the camera’s rotation in position Dimensions: 81mm x 30 mm / weight: 190g The option of using 6 long or 6 short fixing screws for the rotator The Vixen 60DA Focal adaptor connects your Canon EOS DSLR Camera to a telescope with an appropriate 60 mm Focuser Drawtube Thread. Thanks to the use of new materials and an improved design Vixen was able to considerably uprate both precision and durability, when compared to conventional rotational camera adaptors. Two sets of rotational locking bolts (Long and Short) are supplied. The longer ones are knurled and easy to turn by hand. The shorter options help to prevent marring of the camera casing, when using certain designs of camera and are also much less easy to turn by hand, increasing security if you need the camera locked in a particular rotational position for longer periods. The large inner dimension of this adaptor prevents vignetting at the edges of the image when using full frame DSLR cameras. Canon EOS-Bayonet fastener made of hardwearing brass, for years of hassle-free use. Increased material quality over conventional adapters provides more stability in use. 6 fixing bolts hold the camera in rotational position for increased sturdiness (standard rotators often only use 4, or less). FEATURES Screw tips with Delrin-tips prevent tilting of the camera and subsequent image distortion. Large inner diameter prevents vignetting. Inner blackening suppresses scattered light. Compatible with 60 mm accessories, when the camera adaptor is taken off. Two rotational bolt sets (Long and Short) are supplied. SCOPE OF DELIVERY 60DA Focal adaptor 6 long and 6 short fixing screws

Vixen VSD90ss Astrograph
Fast 90 mm high-performance astrograph for demanding astrophotographers and observers with 5 lens elements in 5 groups. Due to the complex optical structure with five lens groups and five elements (quintuplet), including two SD (Super ED) lenses and an ED lens (Extra-low Dispersion) , a virtually aberration-free optical system was created. This revolutionary astrograph is compatible with a full-frame digital DSLR or an even larger 44x33 mm camera. The 90 mm astrograph with fast aperture ratio delivers exceptionally sharp, high-contrast and small point stars from the centre to the corners of the field of view. In addition, it is also ideal for visual observation with a very large field of view but also for planetary observation with high magnification. The VSD90ss is designed so that there is a "long peak range" in the adjustment accuracy of the sharpness, so that photographers can always achieve satisfactory results in astrophotography. Even if the focus is not quite precise, round and sharp stars are still shown throughout the entire image field. Illumination without vignetting In most cases, an astrograph also produces optical vignetting (a gradual decrease in light rays towards the edge of the image) This is mainly caused by rear lenses being shaded by the front lenses. Because of this darkening, it is relatively normal for the photographer to have to further edit the image after taking the picture and also have to do some additional so-called flats before taking the picture. To solve this problem, the VSD90ss uses wide aperture lenses in the rear elements, securing over 90 % of the light volume at the edge of the 60 mm image circle. Since the light intensity is uniform throughout the entire image field of the VSD90ss, there is no need for complex technology to prevent edge darkening. The VSD90ss is coated with the most modern coatings of extremely high reflectivity. These coatings have been specifically developed to optimize the properties of each individual lens element without degrading contrast and light intensity across multiple lenses. Numerous gradations of light bring beautiful point-like stars into the image field The low optical vignetting ensures sufficient illumination and thus eliminates the asymmetric flare caused by bright, diffraction-limited stars. It prevents stars at the edge of the 60 mm image circle from exhibiting deformations such as comets, astigmatism or coma. Since the illumination of the image field is relatively similar from the center to the edge of the image, you can expect excellent star imaging. Please note: *Depending on the recording system used, mechanical vignetting can still occur due to the camera body or incorrect adapters. 96.7% Strehl for impressive visual observations The VSD90ss offers a flattened large field of view with a low magnification wide angle eyepiece. Even with a high-quality wide-field eyepiece with a large field of view, you can get sharp images of stars in the entire field of view when visually observing! In the centre of the field of view, a Strehl intensity of an impressive 96.7% is achieved at visible wavelengths. This Strehl ratio exceeds that of the SD81SII apochromat at 95.7%, which is known for its excellent optical properties, and this also works excellently when observing the moon and planets at high magnification. The versatile large and stable focuser The VSD90ss has a large focuser with a diameter of 87.5 mm to make optimal use of the large illumination field of 60 mm. With the large extension that is compatible with many accessories, it is perfect for astrophotography up to large format or 35 mm full frame DSLR cameras. Thanks to its precise manufacturing, it is also suitable for very heavy cameras without tipping. The precision locking lever of the eyepiece extension The focuser's extension tube has a locking lever that holds the extension tube firmly in position even when using heavy cameras such as large format cameras or CCD cameras with a large sensor. The locking lever clamps the rack gear to the extension barrel so that the viewing angle or focus on your camera does not shift. Compatible with motor driven focusers An optional two-speed motor focuser (not included) is available for the VSD90ss to provide sensitive focusing. An EAF (Electronic Automatic Focuser) from ZWO or equivalent can also be retrofitted. Optional VSD Reducer for even faster results The tried and tested optional VSD reducer, which was also used on the predecessor, the VSD 100, is also compatible with the VSD90ss. The photographer gets even faster results in astrophotography with an aperture ratio of 1:3.9. CHARACTERISTICS 90 mm aperture, 495 mm focal length (F5.5) Needle-fine stars up to the image field edge in 44x33 mm format 5 lens elements in 5 groups Image illumination up to 60 mm Resolution power: 1.29 Limit size: 11.5 Light gathering capacity: 165x Illumination: 60 mm Dimensions: 115 mm diameter x 600 mm length (476 mm length for storage) Weight: 4.3 kg Connections/Thread: Size thread/84 mm (pitch 1 mm), 60 mm (pitch 1.0 mm), 42 mm for T-ring push fit / 60.2 mm, 50.8 mm and 31.7 mm Solar observation: separately available solar projection approach B Optional VSD100 reducer compatible (opening ratio F: 3.9) SCOPE OF DELIVERY VSD90ss high performance astrograph

Vixen SD81SII Telescope OTA
A new 81 mm apochromatic refractor with high-performance Super ED glass (= SD). The advantage of these SD refractors is their short length and low weight.The FPL53 glass reproduces an extremely clear and sharp image due to an exceptionally high elimination of residual colour errors. The SD glass is designed to bring all rays of violet, red, blue, yellow and green together very precisely on the same plane. Thus, the special lens material reduces chromatic aberration across all colours.The new Vixen SD81SII no longer uses spacer plates, which leads to significantly better image quality, especially with bright stars. This means that there are no more spikes on the stars in photographic images, which were otherwise produced by the spacer plates. You will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp and with an extremely high contrast. Observe 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 impressively.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-frame SLR cameras.The older ED81SII, ED103S, ED115S refractors were originally designed for the visual observer or the photographer using APS-C cameras. However, the new SD series has been optimised for use with full-frame cameras by inserting new inner baffle rings.The large 60 mm focuser allows heavy cameras to be attached without tilting. The supplied flip mirror allows comfortable observation, even in unfavourable observation situations, and also offers a T2 thread for connecting a DSLR camera.Thus, observing in degree view or at a 90° angle is possible. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope.FEATURESObjective Lens: D=81 mm, multi-coated 2-Lens SD Apochromat without spacer plates No more spikes on the stars Focal Length: 625 mm (f7.7) Resolution and visual limit: 1.43 arcseconds; 11.3 Mag Light gathering capacity: 134x unaided eyesDimensions and weight: 90 mm dia x 585 mm, 3.6 kg Finderscope: XY Red Dot Finder II Adapter and connections: Adapter thread 60 mm and 31.7 mm for T2-ringConnection 50.8 mm and 31.7 mm socket with flip-mirror diagonal mirrorPhotography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor telescope SD81SII Tube rings Flip mirror system Carrying handle Dovetail rail Red dot viewfinder
