Refractor Telescope MERKUR 910

No experience with astronomy yet? Then this extensively configured DÖRR refractor telescope MERKUR 910 is the perfect device for entering the world of astronomy. The stable telescope is easy to use and features a tripod, AZ-2 mount, finder scope, 3 eyepieces, 2-times Barlow lens, diagonal mirror, erecting lens and a moon filter. The MERKUR 910 enables impressive observations of the moon, planets, stars, brighter nebulae and star clusters. Even details like Saturn's ring become visible. A carefree start into the endless expanses of the universe - suitable for every age group.

The DÖRR MERKUR 910 is a lens telescope - also known as a refractor. The light is collected by the lenses, bundled and magnified by the eyepiece. This is the classic construction. As early as 1609, Galileo Galilei presented the world's first telescope - a refractor. To date, the optics have been constantly improved. The MERKUR delivers a good optical quality. The long focal length of 910mm and the aperture of 60mm make even distant celestial bodies visible. Due to high production numbers and machine manufacturing, telescopes are affordable for amateur astronomers and beginners now.

The telescope rests on a LT2 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 two-axis alt-azimuth fork mount AZ-2 allows you to align the telescope and to track celestial objects. With one axis you may set the azimuth (the cardinal direction). The other axis is responsible for setting the altitude (the height above the horizon). The height axis features a fine movement via a rotary spindle. The setting is done manually on sight. Two tube clamps allow the telescope to be positioned on the mount and keep the telescope in optimal balance. The alt-azimuth AZ-2 mount is especially beginner-friendly because the telescope does not have to be aligned beforehand. This saves time and prevents stress. You can set up the telescope and start your observations immediately.

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 precisely adjusted using two rotary wheels. 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 MERKUR comes with 3 eyepieces. They are equipped with a standardized 1.25" socket diameter:

The DÖRR MERKUR 910 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 MERKUR 910 is 120x. 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.

Every telescope produces a reversed and upside down image. The diagonal mirror, which is inserted between the telescope and the eyepiece, corrects the upside down image. The diagonal mirror also deflects the image by 90° and thus enables a more pleasant view from above.

The erecting lens is mounted between the telescope and the eyepiece. Unlike the diagonal mirror, the erecting lens puts the image back upright and also in the right direction. This means that distant objects on earth can also be observed, such as ships at sea or distant mountain peaks. In addition, the image is enlarged by a factor of 1.5x:

*the recommended maximum magnification for the DÖRR MERKUR 910 is 120x. 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.

Note: Please do not combine the erecting lens with the Barlow lens. This leads to blurred images.

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.
