Vixen polar meter QPL Compass for Polar Star Alignment

NASA is constantly working to travel deeper into space and reveal the exciting secrets of our universe. With the ISA Space Exploration NASA-themed 76/350 telescope, you can go on your own journey of discovery through the night sky. The complete astronomy kit comes with everything you need for stargazing – a reflector telescope, an altazimuth mount, a tripod and an extensive range of practical astronomy accessories. Simply point at the night sky and start exploring – the entry-level telescope with NASA theme comes fully preassembled and is very easy to use. It also includes a sun filter for safe solar observations. Entry-level telescope for exploring the night sky Featuring a 76 mm aperture, a 350 mm focal length and an aperture ratio of approximately f/4.6, the powerful reflector telescope is particularly well-suited to wide-field observations, and produces stunning images of star clusters such as the famous Pleiades and the giant Orion’s nebula. In addition, the astronomical telescope is also great for exploring our own solar system: go an exciting journey across the surface of the moon, take a peek at the gas giant Jupiter with its moons, or marvel at the rings of Saturn. And if you want to view things from a different perspective, you can quickly change the magnification thanks to the two included eyepieces and 2x Barlow lens. Important: “Newton” type reflecting telescopes are ideal for astronomical observations, but are not suitable for observing wildlife and landscapes. For terrestrial observations, we recommend refracting telescopes. Intuitive entry-level telescope for beginner astronomers Less time setting up means more time to look at the stars: this beginner’s telescope comes fully preassembled so that you can get started straight away with your night sky observations. What’s more, the altazimuth mount, which is attached to the telescope via a sturdy tripod, is also very easy for beginners to use. As with a standard camera tripod, you simply pivot the telescope up and down or left and right with your hand – perfect for roaming between different night sky objects. And thanks to its compact and portable design, the telescope is also ideal for taking on holiday. Fully equipped starter set for solar and night sky observations The Parker Solar Probe was NASA’s first successful attempt to “touch” the sun. Although you can’t get quite as close with the ISA Space Exploration NASA-themed telescope, you can attach the included sun filter to safely observe sun spots, planetary transits and solar eclipses. WARNING: Never point the telescope at the sun without the solar filter! In addition, whether you’re observing the sun, moon, planets or stars, you can use the included smartphone camera adapter to attach your smartphone camera to the eyepiece and turn your telescope into a lens for capturing images of your exciting astronomical discoveries. The set also comes with astronomy software and a lunar map to help you find objects of interest.

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.
