Warning notes

General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
Do not expose the device to high temperatures.

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 VSD70SS F5.5 Astrograph Telescope

Fast 70mm high-performance astrograph F5.5 designed for demanding astrophotographers and observers, featuring 5 lens elements in 5 groups With its sophisticated optical design incorporating five lens elements in five groups (Quintuplet), including two SD (Super ED) lenses and one ED (Extra-low Dispersion) lens, this astrograph delivers a virtually aberration-free optical system. The convex lens utilises two SD lenses and a high-refractive ED lens, while the front lens is crafted from a newly developed high-performance lanthanum glass. Perfect for astrophotography and visual observation This revolutionary astrograph is compatible with digital full-frame DSLRs and even larger 44 x 33 mm cameras. With its fast F5.5 aperture ratio, the 70mm astrograph produces exceptionally sharp, high-contrast, pinpoint stars from the centre to the very edges of the field of view. Not only is it ideal for astrophotography, but it also excels in visual observation, offering a wide field of view for deep-sky objects and delivering stunning detail in planetary observation with high magnification. Consistently sharp imaging across the entire field The VSD70ss is designed with a long peak range in focus adjustment accuracy, making it easier for astrophotographers to achieve consistently outstanding results. Even if the focus isn’t set perfectly, stars remain round and sharp across the entire image field. The VSD70ss is very temperature-resistant so that you always keep a very stable focus point. Minimal vignetting for uniform illuminationMost astrographs experience some level of optical vignetting (light gradually diminishes towards the image edges). This is mainly caused by the rear lenses being shadowed by the front lenses. As a result, photographers often need to apply image corrections or capture additional flat frames beforehand. The VSD70ss tackles this issue with large-aperture lenses in the rear elements and preserves over 90% of the light all the way to the edge of its 55mm image circle. The result is uniform brightness across the entire field, eliminating the need for extensive post-processing to compensate for edge darkening. The VSD70ss features cutting-edge multi-coatings with exceptionally high reflectivity. These coatings have been specially designed to optimise the performance of each individual lens element, ensuring maximum contrast and light transmission without degradation across multiple lenses. Note: *Mechanical vignetting may still occur depending on the camera system used, particularly due to the camera body or incorrect adapters. 96.7% Strehl for stunning visual observations When paired with a wide-angle eyepiece with low magnification the VSD70ss offers a flattened large field of view. Even with a high-quality wide-field eyepiece with a large field of view, stars appear sharp across the entire field of view during visual observation. At the centre of the field, the telescope achieves an impressive 96.7% Strehl intensity at visible wavelengths—surpassing even the acclaimed SD81SII apochromat with its 95.7% Strehl ratio. This superior optical quality is also evident when observing the Moon and planets at high magnifications. Large, versatile, and stable focuser The VSD70ss has a large focuser with a diameter of 87.5mm to make optimum use of the large 55mm field of illumination. Designed to support a wide range of accessories, this large focuser is perfect for astrophotography, accommodating everything up to large-format cameras or 35mm full-frame DSLR cameras. Its precision manufacturing ensures excellent stability, preventing any tilting even when using heavy imaging equipment. Optional VSD reducer for even faster resultsThe new reducer has been specially developed for the VSD90ss and the VSD70ss. At a focal ratio of 1:3.9. the photographer gets even faster results in astrophotography. Compatible with motorised focusersTo enable sensitive focusing, an optional dual-speed motor focuser is available for the VSD70ss. Additionally, an EAF (Electronic Automatic Focuser) from ZWO or a compatible system can be retrofitted.
