The R200SS features very fast f4 200 mm optics with a parabolic primary mirror and produces extremely sharp images with no chromatic aberration. A special layer made using state-of-the-art technology provides an optimal surface for observing and photographing deep-sky objects. The large aperture and short size make this device ideal for astrophotography of nebulae, star clusters and comets. The use of an optional coma corrector provides a sharp image until the edges of the field of view. The focuser features a socket for 2-inch eyepieces. Vixen has developed a unique aluminium vacuum evaporation system that produces extreme precision mirror surfaces. The revolutionary Vixen system allows for controlled coating of the primary mirror for greater accuracy. This coating is used on both the VC200L and the R200SS.

Whether for school, university, or a hobby, the high-quality BRESSER Biorit SE 1600x Microscope is perfect for a wide range of applications. Thanks to the optional battery operation, it’s also portable. The adjustable LED lighting of the Biorit SE 1600x ensures ideal illumination, with separate controls for both transmitted and incident light, allowing you to dim each light independently. The microscope offers a magnification range of 40x to 1600x, and the 2x Barlow lens allows for additional zooming. Precise observations are supported by the coarse and fine focus adjustments. To protect your samples, the 40x objective lens is spring-loaded. The colour filter wheel makes it easy to highlight different details of your samples. With a modern design and a rear-facing revolving nosepiece, the microscope is extremely user-friendly. The Biorit SE 1600x also features a 360° rotatable monocular viewing head, and it can be powered via a computer or power bank (not included) using the included USB cable and power adapter.

Super robust flight-case suitable for all Explore Scientific ED102 APO telescopes with white aluminum tube.

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.

Focal length reducer for the VSD90ss and VSD70ss with two ED lenses designed for high-end astrophotographyThe two ED lenses maximise the photographic performance of the VSD90ss and the VSD70ss, which are designed for both photography and visual observation. The reducer can illuminate an image circle of 44 mm (suitable for a 34x36 full-frame format). The reducer has a very sophisticated design as it contains four elements in four groups, including 2 ED lenses. Thanks to its larger lens diameter, it offers significantly improved image illumination compared to its predecessor, the smaller V0.79x reducer. The star distortion at the edges is also reduced to an absolute minimum.The focal length of the VSD90ss telescope is shortened by about 0.71x and the focal ratio is reduced from 5.5 to 3.9. This results in a super-fast f3.9 astrograph, capable of fully illuminating a full-frame DSLR camera.FEATURES    Magnification: 0.71x    Focal length VSD90ss: from 495 mm (F5.5) to 351 mm (F3.9)    Illumination: 44 mm    Lens design: 4 elements in 4 groups, including 2 ED lenses    Coatings: AS coatings (99% light transmission per surface)    Connection thread: M84mm, pitch 1 mm (male thread)    Connection thread for a camera: M60 mm, pitch 0.75 mm    Filter thread: 60 mm diameterSCOPE OF DELIVERY    Focal Reducer V0.71x    2 mm Allen keys    Dust caps
