Optical Tube Assemblies

Specification and optics same as Startravel-80 but comes with 45º Erect Image Diagonal, and supplied without Equatorial Mount and Tripod. Complete with tube rings.

90MM (3.5") F/1250 MAKSUTOV-CASSEGRAIN TELESCOPE

Magnifications (with eyepieces supplied): x50 & x125
Highest Practical Power (Potential): x180

Offers the same high contrast, high magnification Maksutov optics as the Skymax-90 but has more aperture.

Highest Practical Power (potential):x300
Diameter of Primary Mirror: 150mm

Sky-Watcher EVOSTAR telescopes are classic two-element, air-spaced, achromatic refractors. They are outstanding, high-performance, high-resolution instruments manufactured to high standards of optical and mechanical precision.

120mm (4.75") f5 Refractor

Diameter: 120mm
Telescope Focal Length: 600mm (f/5)
Eyepieces Supplied (1.25"): 10mm & 25mm

The new Sky-Watcher EXPLORER-150PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-150P Black Diamond Series, but with two significant advantages.

A compact but powerful, high-contrast, high-resolution Maksutov-Cassegrain telescope. High-transmission multi-coatings are employed on all optical surfaces for optimum performance.

The Sky-Watcher EVOSTAR series are two-element, air-spaced, multi-coated objective achromatic refractors. They are truly outstanding, high-performance, high-resolution instruments manufactured to extremely high standards of optical and mechanical precision

All Skywatcher f/5 (‘fast’) Newtonian Reflectors and Dobsonian models feature high-quality parabolic primary mirrors to eliminate spherical aberrations inherent in ‘fast’ focal length reflector.

The new Sky-Watcher EXPLORER-200PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-200P Black Diamond Series, but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also the tube length has been slightly shortened to optimise performance for prime-focus photography

The new EVOSTAR DS-PRO Series ED Apochromatic refractors in their stunning Black-Diamond livery, house premium optics of the same quality and performance level as our now legendary Equinox series, making them superb instruments for both imaging and visual observations.

The new QUATTRO series with their fast f/4 focal ratios, have been specially designed for high quality astrophotography with short exposure times. They are of course also fine telescopes for visual observations.
