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.

Magnifications (with eyepieces supplied): x52 & x130
Highest Practical Power (Potential): x204

102mm (4") f4.9 Refractor Tube Assembly

Specification and optics same as Startravel-102 (AZ3) but supplied without Equatorial Mount and Tripod. Complete with tube rings.

The new Sky-Watcher EXPLORER-130PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-130P Black Diamond Series, but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision.

Magnifications (with eyepieces supplied): x30, x60, x75, x150
Highest Practical Power (potential):x300
Diameter of Primary Mirror: 150mm

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.

120mm (4.75") f5 Refractor

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

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.

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