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.

The new BRESSER NANO AZ telescopic mount has been developed to ensure quick and easy operation. The mount is as easy to use as a photo tripod, it is just more stable and easily carries telescopes weighing up to 4 kg. The mount can be easily swivelled by hand to the left, right, up and down, making it really easy to use and with a weight of only 3.4kg, the mount is also easy to transport. Ideal for the easy entry, as a travel mount or for "quick observations". The telescopes are securely held by a clamp for 44mm prism rails, the so-called GP Level. This is an international manufacturer-independent standard, whereby all telescopes with such a GP prism rail can be installed on this mount. For example our BRESSER MESSIER lens telescopes AR-90s, AR-102xs, AR-102s, or our small Maksutov-Cassegrain telescopes MC-90 and MC-102.

BRESSER Twilight I telescope mount with tripod

The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder. Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod

Vixen SD81SII Telescope OTA

A new 81 mm apochromatic refractor with high-performance Super ED glass (= SD). The advantage of these SD refractors is their short length and low weight.The FPL53 glass reproduces an extremely clear and sharp image due to an exceptionally high elimination of residual colour errors. The SD glass is designed to bring all rays of violet, red, blue, yellow and green together very precisely on the same plane. Thus, the special lens material reduces chromatic aberration across all colours.The new Vixen SD81SII no longer uses spacer plates, which leads to significantly better image quality, especially with bright stars. This means that there are no more spikes on the stars in photographic images, which were otherwise produced by the spacer plates. You will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp and with an extremely high contrast. Observe the ring planet Saturn or the cloud bands on Jupiter.But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed impressively.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, this refractor allows illumination with a 44 mm image circle for full-frame SLR cameras.The older ED81SII, ED103S, ED115S refractors were originally designed for the visual observer or the photographer using APS-C cameras. However, the new SD series has been optimised for use with full-frame cameras by inserting new inner baffle rings.The large 60 mm focuser allows heavy cameras to be attached without tilting. The supplied flip mirror allows comfortable observation, even in unfavourable observation situations, and also offers a T2 thread for connecting a DSLR camera.Thus, observing in degree view or at a 90° angle is possible. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope.FEATURESObjective Lens: D=81 mm, multi-coated 2-Lens SD Apochromat without spacer plates No more spikes on the stars Focal Length: 625 mm (f7.7) Resolution and visual limit: 1.43 arcseconds; 11.3 Mag Light gathering capacity: 134x unaided eyesDimensions and weight: 90 mm dia x 585 mm, 3.6 kg Finderscope: XY Red Dot Finder II Adapter and connections: Adapter thread 60 mm and 31.7 mm for T2-ringConnection 50.8 mm and 31.7 mm socket with flip-mirror diagonal mirrorPhotography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor telescope SD81SII Tube rings Flip mirror system Carrying handle Dovetail rail Red dot viewfinder
