The 90/900 refractor telescope is a classic achromatic refractor and can be used for either astronomy or nature observations (e.g. of wild animals). The long focal length (900 mm) makes the telescope a specialist for observing the Moon, planets and bright objects outside our solar system. Saturn's majestic rings and giant storms on Jupiter can be seen, as well as the brighter emission nebulae, galaxies and star clusters if you observe on a dark, moonless night away from city lights. The sturdy equatorial mount can be aligned to the Pole Star, Polaris, and makes tracking objects by hand child's play.Three eyepieces, a 20mm, 12.5mm and 4mm, giving 45x, 72x and 225x magnification respectively, are included and also a 3x Barlow lens and Moon filter as standard.  A red LED reflex finder, once aligned to the telescope's main optical axis, will help you find your way to a huge array of potential targets for observation in the night time sky.The EQ3 mount is provided with slow motion flexible cables to help you follow objects accurately and compensate for the effects of the Earth's rotation.  The mount can also be upgraded to a simple RA motor tracking kit with additional purchase.FEATURESOptical System: Achromatic RefractorLens diameter: 90mmFocal length: 900mmMagnification: 45x-675xMount: EQ3, equatorialTripod: Aluminium with accessory traySCOPE OF DELIVERYOptical TubeMountAluminium tripodEyepieces 31.7mm (1.25"): H-20mm, H-12mm, SR-4mm3x Barlow LensMoon filterLED viewfinderStar map

With its 114-mm aperture, this telescope collects three times more light than a 76-mm telescope. Therefore, fainter objects become visible, and you can see more details of the moon and planets. Nevertheless, the telescope is very compact and sets up quickly, with no assembly required, so it can be transported to your favourite night-sky-observation location easily. Use is very intuitive, without compromising stability. The built-in accessory tray keeps the eyepieces handy, and the red-dot finder makes locating objects simple.Please note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest refractor (lens) telescopes for landscape and nature observing.

Featuring a large mirror with a high focal length, this telescope allows you to observe a wide range of night sky objects. Thanks to the catadioptric system (integrated Barlow lens), the tube has a short design-despite the high focal length-making the telescope highly portable. The BRESSER Spica Plus also comes with high-performance mechanics, including a premium equatorial mount that allows you to set up the telescope in no time. A focuser is attached to the side of the tube, as is standard on a Newtonian reflector telescope. It comes with two eyepieces for observing at different magnifications. Explore the planets of our solar system and discover new worlds. And if you’d like to capture your observations to share with others, you can take photos through the telescope using the supplied smartphone camera adapter. Please note that Newtonian reflecting telescopes are ideal for astronomical observations, but are not suitable for observing wildlife and landscapes. For observing wildlife and landscapes, we recommend BRESSER refracting telescopes.FEATURESTelescope for observing the night sky and the sunOptical system: Newton reflectorMax. useful magnification: 260xLens diameter: 130 mm Focal length: 1000 mm Aperture ratio: f/7.7Mount: Equatorial mountEyepiece diameter: 31.7 mm (1.25”) DELIVERY CONTENTTelescope with mountLens sun filterMoon and planet filter set (4 pcs)Eyepieces: 4 mm, 20 mmLED finder scope3x Barlow lensSmartphone cameraAluminium tripod Accessory trayAstro R-Lite torch

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.
