FAQ - Frequently Asked Questions

That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

  • Alt-azimuth: easy to use, moves horizontally and vertically
  • Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

  • Moon: from 30 mm
  • Planets: from 100 mm
  • Deep sky: from 150 mm

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.

Vixen R200SS Reflector Telescope
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. FEATURES Very quick 200 mm F 4.0 optics Focal length: 800 mm Resolution and limiting magnitude: 0.58, 13.3 Light-gathering power: 816x Dimensions and weight: 232 x 700 mm; 5.3kg Adapter and connections: 31.7 mm receptacle, 60 mm connection DELIVERY CONTENT R200SS telescope/tube 7x50 viewfinder, illuminated Tube clamps Dovetail bar Carry strap for telescope

Vixen VC200L Optical tube
Astrophotographers generally use two different focal lengths: Short focal lengths for overview photos and extensive deep-sky objects, and long focal lengths for objects which are further away. Our aspherical mirror optics offer the perfect solution for these scenarios. The VISAC primary mirror (Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and provides a fully flat and true-colour image over the entire image frame. Thanks to the three-element field corrector in front of the convex secondary mirror, there is no spherical aberration, coma or field curvature. Although the device is designed for astrophotography, it is also suitable for visual observations. FEATURES Photographically optimized thanks to field flattener lens Revolutionary coating technology High light-gathering power Photographically optimised optical system Built-in field flattener lens 200 mm aperture and 1800 mm focal length Optional reducer availableBackfocus without Reducer: 142,9 mmBackfocus with Reducer: 63,5 mmWeight: 6.9 kg DELIVERY CONTENT VC200 reflector telescope Carry handle 7x50 finder scope (illuminated) Flip mirror Dovetail adapter

Vixen AP Mount with manual fine Adjustment
The AP mount provides a secure, stable support for your telescope. Thanks to the slip clutch mechanism, the mount can be adjusted quickly to the target object. There is a wide range of optional accessories. The ADVANCED POLARIS mount is perfect for both beginners and advanced observers who require a lightweight travel mount. STYLISH DESIGN The AP mount features an ultra-smooth finish without any projecting parts. Simply place your telescope on the mount and move it to the desired celestial object without having to loosen any clamps! QUICK POLAR ALIGNMENT The slip clutches allow you to adjust the telescope to your target object easily – no more searching for adjustment clamps in the dark! An optional polar meter is available, which enables you to locate the celestial pole when it is hidden by trees or buildings. OPTIONAL POLAR FINDER SCOPE The innovative polar finder scope provides a new way to polar align your telescope. Simply align the stars in the crosshair reticle with the same stars in the night sky. Polar alignment is achieved using 3 reference stars. The polar finder is illuminated to facilitate orientation and switches off automatically after 3 minutes to save battery power. OPTIONAL POWER SUPPLY The RA and DEC motor modules are powered by four AA alkaline, Ni-MH or Ni-CD batteries. The RA motor module has a USB Micro-B port for an external power supply.

BRESSER Messier NT-150S/750 Hexafoc EXOS-1/EQ4 Telescope
NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.The BRESSER Messier NT-150 telescope excels with high rigidity and tack-sharp parabolic optics. The 150 mm aperture enables you to observe bright nebulas in the depth of space. Find the remnants of a gigantic stellar explosion from the year 1054 in the Taurean constellation, or scan the glowing bands of the great Orion Nebula. Detect the famous Whirlpool Galaxy in the Big Dipper or find the Dumpbell-Nebula in the constellation Vulpecula (little fox). The high rigidity of the EXOS-2 mount allows for relaxed observations and is helpful for those making their first attempts at astrophotography.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.
