Bresser Messier NT-130S / 650 parabolic Optical Tube Newton

Messier NT-130S / 650 Optical Tube

Precisely manufactured parabolic mirror, ideal for observation and astrophotography. This telescope is only an optical tube without mount and tripod.

Basics:

There are not only alternators in the car! :-)
Newton telescopes are considered (and are) basically high-powered telescopes. From f / 5 I define again as particularly bright. When observing the moon, we definitely recommend a filter to reduce the glare effect. - The moon reflects so much light that the light should be attenuated (especially at low magnification). Also note the dark adaptation of the eye. For example, if I want to observe deep sky objects after the moon, the adaptation of the eye takes a certain amount of time before I can perceive the much fainter ones again in detail.
And that brings us to the objects that such a Newton can show in abundance - visually and photographically!
Deep sky objects (ie galaxies, nebulae, star clusters ...) do not require a high magnification, but a corresponding light gathering power. For photography, this also means the shortest possible exposure time for a shot.
Planets (and moon) require a higher magnification and thus a Barlow lens ???? for focal length extension.
So with this device also beautiful details on the moon and planets can be seen! So you do not have to do without this field of application:
An (almost) all-rounder among the telescopes focusing on deep sky.


30% more light through the 130 mm opening compared to the standard in this price range devices with 114mm opening characterize this device. The pure color reproduction and easy transportability enable planetary observation due to the good optical performance, deep sky objects move into the observation area. Delight in the color of bright stars, such as of the double star Albireo in the constellation Swan, or choose the quadruple system Epsilon Lyrae in the constellation Lyre as a target.

Its 260x maximum useful achievable magnification offers beautiful lunar and detailed planet observations (such as the rings of Saturn, moon shadow games on Jupiter or its large red spot). Interesting deep-sky excursions to brighter objects, such as the Orion Nebula, the open double star cluster (h and chi) in Perseus or even the galaxy groups M81 are focal point of the telescope (because of the short focal length).
Due to the short focal length, we recommend a Barlow lens for moon and planet observation.

Unlike the longer focal length model, this unit is designed for deep sky objects and wide field observation.

A suitable device for school astronomy.
