FAQ - Frequently Asked Questions

Why do I see everything upside down and mirrored in the finder?

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

What is the difference between an alt-azimuth mount and an equatorial mount?

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

What minimum apertures do I need for certain objects?

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

Product information "Vixen AX103S apochromatic Refractor - optical Tube"

The AX103S is a top-of-the-range ED apochromat in the refractor series. It features a triplet ED object lens and a rear-mounted field-flattener lens.
The f8.0 refractor contains a central ED lens in the objective and reduces chromatic aberration to an absolute minimum.
An optional focal reducer can reduce the aperture ratio to 1:5.6 in order to provide quicker results for astrophotographers.
The built-in field flattener lens provides a sharp image across the entire field of view – an essential requirement in astrophotography. The 60 mm ring on the focuser allows you to attach a 2’’ eyepiece or accessories and a camera adapter. The AX103S is specially designed for photography, but also offers stunning visual performance, especially for observing the moon and the planets.
The AX 103S is corrected for full frame photography and provides razor-sharp pictures right into the corners of the image field.
This telescope is guaranteed to provide a lifetime of outstanding performance!

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 SG-L02 Headlamp red-light white-light

The perfect LED head torch for nighttime observations! Adjusting your eyes to the dark surroundings is very important when making astronomical observations. In dark areas, it is very difficult to use astronomical equipment without a suitable light. With normal lights, however, the light intensity is more important than protecting your eyes against bright light. Using these lights at night makes your pupils contract, which can make it difficult for your eyes to readjust to the darkness. The SG-L01, our first astronomy LED lamp, featured a built-in red LED that provided a solution to this problem. However, the red light did not offer optimal visibility. On our new astronomy LED light, the SG-L02, the LED lights produce warm light to improve visibility. They also ensure that your eyes stay adapted to the dark. The LEDs do not emit light in the sensitive range of 555 nm. The brightness of the white light can be adjusted between 3 and 42 lumen, while the red light can be adjusted between 0.28 and 7.62 lumen. FEATURES Dimmable red light ensures that your eyes stay adapted to the dark Built-in rechargeable battery, charges via USB Waterproof design LED colour can be switched from red to white 0.28 to 7.62 lumen for red light 3 to 42 lumen for white light Dimensions: 41 mm x 33 mm x 30 mm Weight: 29 g DELIVERY CONTENT SG-L02 head torch Strap (size S) Strap (size L) Pocket clip Cable for charging the battery (USB-A plug to USB Micro-B plug)

BRESSER Messier 6" Dobson

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 6'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. Not only for beginners - also enthusiastic and experienced amateur astronomers love this high perfomance and compact telescope for traveling and to discover the night sky. The main goal of this telescope is the quick setup and the ease of use. Simply put the Messier 6'' Dobson telescope on a table in your backyard, point the telescope to your target object and you are ready to start your observation. The Messier 6'' Dobson is almost pre-assembled ex factory which means you can start within minutes. With the included standard accessories (LED-finder, 25mm and 9mm Kellner eyepieces and Moonfilter) the telescope is ready for observing. The inbuild compass and circular level speeds up the telescopes orientation. The optical diameter of 150mm (6'') does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. Finding and observing is much easier with that light gathering richfield telescope. Bresser also has equipped these dobsonians with a high quality parabolic main mirror which offers a much better scharpness and contrast than other telescopes with a simple spherical main mirror. In addition, this telescope has a particularly large secondary mirror of 55mm in diametre for ideal illumination of the image field. The 6'' Dobsonian is also equipped with a large 2.0'' focuser, which allows the use of 2.0'' eyepieces with even larger fields of view. Due to the included eyepiece adapter 2'' to 1.25'', all 1.25'' eyepieces can of course be used. The optical tube can easily be moved inside the tube rings in order to find the optimal balance and observing position. This is another virtue of this highly versatile telescope system: Remove the optical tube from the dobsonian telescope mount and use the optics on a equatorial mount - in minutes. This telescope is setting a new standard in usability, versatility and performance in its price class.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 BRESSER refractor (lens) telescopes for landscape and nature observing.
