Reflector Telescope SATURN 900

The extensively configured DÖRR reflector telescope SATURN 900 is the ideal device for beginners with ambitious standards. But also advanced astro users will have fun with the mirror telescope. The very stable telescope is easy to use and features a tripod, EQ2-mount, finder scope, 3 eyepieces, 2-times Barlow lens and a moon filter. The SATURN 900 ensures impressive observations of the moon, planets, stars, brighter nebulae, open star clusters and globular star clusters. Even details of larger planets such as Saturn's ring or Jupiter's moons become visible.

The DÖRR SATURN 900 is a reflector telescope or mirror telescope based on the Newton construction. This design has proven itself over a long period of time. Generations of astronomers preferred the Newtonian design because of its various advantages. Despite the large focal length of 900mm and a 114mm aperture, the telescope tube is relatively compact. This is achieved by deflecting the light using the primary and secondary mirrors. The mirrors not only make the telescope more compact, but also ensure that there are no chromatic aberrations - as can occur with refractor telescopes. The SATURN delivers a very good optical quality. The Newton construction of astronomical telescope offers a lateral view. This ensures pleasant and fatigue-free observation fun without having to bend down. Since mirrors are easier to produce than lenses, the SATURN 900 offers an excellent price/performance ratio.

The telescope rests on a LT1 tripod with aluminium tripod legs. It combines high stability with low weight. This is a great advantage if you want to transport the telescope. The height of the tripod legs can be variably adjusted to ensure comfortable observation in an upright position - regardless of your body height. The triangle tray between the tripod legs is ideal for keeping eyepieces and other accessories while observing.

The EQ-2 equatorial mount enables the telescope to be aligned and celestial objects to be precisely tracked. The axes are aligned with the Earth's axis. As a result, only one axis has to be moved to compensate for the arc-shaped rotation of the earth. Exact tracking of the celestial bodies to be observed can be carried out evenly. The observation object always remains in the centre of the field of view. Therefore, the EQ-2 equatorial mount is also well suited for high magnifications. The movement of the polar and the declination axis as well as the tracking is done manually via rotary knobs for fine movement, each attached to a flexible shaft. The movable counterweight and the two tube clamps, which allow the telescope to be positioned precisely on the mount, keep the telescope in optimal balance.

The components of the telescope can be set up easily and quickly. Operating the telescope is also quite simple. While you track the objects manually, the sharpness can be adjusted precisely using two rotary wheels. The tracking knob rests on a flexible shaft and can be positioned exactly to ensure comfortable operation for any body height. All setting options are designed in such a way that even beginners are able to intuitively operate the telescope immediately. Whether children, teenagers or adults - nothing stands in the way of a successful start in the world of astronomy.

The finder scope is placed parallel to the telescope tube and, after a one-time adjustment, allows you to quickly find the desired celestial objects that you want to observe. A finder scope is necessary because the viewing angle of telescopes is so small due to the high magnification that it is not possible to find celestial objects. Due to the low magnification of only 5x, the finder scope captures a larger area of the sky, making it easier to quickly align the telescope to the desired object.

The eyepieces are part of the optical system. They are attached to the telescope and allow you to look into the telescope. The eyepiece used affects the magnification of the telescope. The SATURN comes with 3 eyepieces. They are equipped with a standardized 1.25" socket diameter:

The DÖRR SATURN 900 also includes a 2x Barlow lens. It is mounted between the telescope and the eyepiece and it doubles the magnification. The following magnifications result with the Barlow lens:

*the recommended maximum magnification for the DÖRR SATURN 900 is 228x. Although higher magnifications are technically possible, they no longer lead to sharp observation results. Mainly responsible for this are the air turbulences in our earth's atmosphere.

The moon is illuminated by the sun. During full moon, it is uncomfortably bright when looking through the eyepiece. The supplied moon filter is screwed into the back of the eyepiece and neutrally darkens the image. Basically, it works like sunglasses and even longer observations of the full moon are pleasant and possible without being blinded. The use of the moon filter is also recommended when observing Venus in order to reduce the glare.

• NEVER look directly at or near the sun through the telescope or viewfinder! Risk of blindness!

• The telescope is not a toy! Children are not allowed to use the telescope without adult supervision.
