Reflector Telescope ORION 1000

The extensively configured DÖRR reflector telescope ORION 1000 is the ideal device for advanced hobby astronomers with high demands. The extremely stable telescope is easy to use and features a tripod, EQ5-mount, finder scope, 3 eyepieces, achromatic 2-times Barlow lens with camera connection and a moon filter. The ORION 1000 ensures impressive observations of the moon, planets, stars, brighter nebulae, open star clusters and globular star clusters. Even details of larger planets and very distant galaxies become visible.

The DÖRR ORION 1000 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 1000mm, the telescope tube is still more compact than a lens telescope with comparable data. 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 large telescope aperture of 200mm is also quite impressive. It ensures a very high light intensity of f5, which is same important for astronomical observations as a large focal length.

The ORION delivers excellent optical quality, for which the parabolic primary mirror is partly responsible. This special mirror is produced quite elaborately using the latest manufacturing technology. But the effort is worth it and the parabolic mirror prevents aberrations and reduces diffraction blur. Details are reproduced much sharper and with higher contrast. The Newton construction of the ORION offers a lateral view. The Newton construction of this 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 ORION 1000 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 equatorial mount EQ-5 is the most stable mount from DÖRR and 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-5 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. Two movable counterweights 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 9x, the finder scope captures a larger area of the sky, making it easier to quickly align the telescope to the desired object. The large aperture of 50mm ensures a high light intensity for even better orientation.

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 ORION comes with 3 eyepieces. They are equipped with a standardized 1.25" socket diameter:

The fully coated lenses (FC) enable improved light transmission for the brightest possible image and reduce reflections.

The DÖRR ORION 1000 includes an achromatic 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 achromatic Barlow lens is fitted with a T2 thread mount. Using the appropriate T2 adapter (optionally available from DÖRR), all common SLR and system cameras can be connected to the telescope for astrophotography. For this purpose, the Barlow lens is inserted into the telescope and connected to the camera instead of an eyepiece. This significantly reduces optical aberrations.

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.
