Sky-Watcher 8" f/5 Newtonian Telescope - OTA
200 mm aperture already show you thousands of nebulae, star clusters and galaxies. The image brightness of the powerful Newtonian optics allows you to zoom in on compact nebulae even higher to see more details. The image remains bright and rich in contrast.
The moderate focal ratio of f/5 allows the use of a relatively compact secondary mirror. This and the proven, diffraction-limited parabolic mirror also make enjoyable planetary observations possible. Up to about 300x magnification can be achieved without any problems and without having to worry about blurring caused by the optics.
Significant advantages for astrophotography
The telescope has a 2" Crayford focuser with 10:1 dual speed for high-precision focusing and offers enough space for the easy connection of all common cameras on the market.
The 2" Crayford focuser with 10:1 dual speed
The new 2" Crayford focuser enables highly accurate focusing for crisp astrophotography. Furthermore, the mechanical stability is very high. Even cameras with more than 2 kg weight are still held well. The scope of delivery includes a reduction to 1.25" barrel size.
Better field correction through Skywatcher coma corrector
Due to physical reasons, a fast Newtonian optics produces distorted stars in the peripheral regions, this is the Newtonian coma.
This telescope is also well prepared for astrophotography, because the telescope can accommodate suitable coma correctors which compensate for this effect and lead to pinpoint stars across the field of view. It works for both observation and astrophotography.
