Description
The National Geographic Retractor 90/900 EQ3 telescope (9070000) is a long-focus achromatic refractor that collects enough light for comfortable tracking of objects in deep space. This classic telescope is, however, good for being careful with terrestrial objects and for watching the bright sky. You can see the majestic rings of Saturn and the giant storms on Jupiter, look at the nebulae and sunrises, see the monthly craters and the Polar Star. You can't see the brightness of the night sky! On a monthless night, this telescope is far from the place to show itself at its best. It is pleasantly surprising to see the wide range of accessories of the telescope, which includes three eyepieces, a Barlow lens, an eyepiece that wraps, a monthly filter, and more, so you can immediately begin both astronomical and landscape observations.
The lens of the National Geographic Retractor 90/900 EQ3 telescope (9070000) has an achromatic refractor with a 1/10 aperture, so this telescope can achieve great magnification when paired with clear long-focus eyepieces. The objective lens has a rich spherical coating to increase light transmission and raise contrast. The lens is equipped with a lens hood to protect against light pollution and dew.
The achromatic lens of the telescope is a guarantee of capturing a clear and undisturbed image. It changes chromaticity and accommodates reduced internal optical reflections. The telescope is equipped with three eyepieces, a Barlow lens and a monthly filter, which is necessary to increase the contrast of the Earth’s natural satellite. The maximum increase “out of the box” is 675 times. Be careful when choosing an object (long fields of vision or, for example, details of the month) and then select a combination of eyepieces and lenses that allows you to capture a wide field of view or great magnification. The telescope is equipped with a dot finder LED-Red Dot Finder. For greater handiness (especially landscape ones), the kit includes a diagonal mirror.
For clear viewing of objects in the bright sky, the telescope is complemented by the German-type EQ3 rigid mount. The installation is equipped with thin mechanisms on both axes. The one is a little more foldable than the mastered one, less azimuthal, and better suited for those who need to be careful. This will make it easier and easier to compensate for the wrapping of the earth's cool and accurately guard the object that will hit you. In the case of thin worm gears, it is possible to install motorized worm gears (and install an auto-guidance system). Coordinate pins allow you to point the telescope at objects based on the equatorial coordinate system. For astrophotography, it is also better to install an equatorial type.
