Equinox-120 PRO OTA  F/900 Fluorite ED Apochromatic Refractor Telescope Equinox-120 PRO OTA F/900 Fluorite ED Apochromatic Refractor Telescope
The Equinox 120 is the star of the Equinox Series. Its generous aperture makes it an ideal observing instrument for solar system and deep space objects alike – and it really shines on double stars. For astrophotography, the Equinox 120 features an f/7.5 focal ratio – more than speedy enough for today’s sensitive CCDs and digital SLR cameras. Plus, it can be coupled with a common SCT focal reducer to achieve even faster speeds.

Equinox-100 PRO OTA  F/900 Fluorite ED Apochromatic Refractor Telescope Equinox-100 PRO OTA F/900 Fluorite ED Apochromatic Refractor Telescope
The Equinox 100 departs slightly from the other refractors in this series. It is designed primarily as a visual instrument for high-power, high-resolution applications. The Equinox 100 features a beautifully corrected ED doublet with a focal length of 900 mm. It provides outstanding views of solar system objects and of brighter DSOs, and can split even the tightest doubles with ease. For added fun, attach a video camera along with our 2” ED 2x Barlow and treat yourself to stunning real-time views of earth’s nearest neighbours!

EXPLORER-150PDS  150mm (6”) f/5 Parabolic Dual-Speed Newtonian Reflector OTA  EXPLORER-150PDS 150mm (6”) f/5 Parabolic Dual-Speed Newtonian Reflector OTA
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 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.

Even better performance for astro-photography and visual use can be achieved when used in combination with Sky-Watcher’s Newtonian coma corrector (Prod.Code 20233).

AN ASTROPHOTOGRAPHERS DREAM TELESCOPE!!

The exciting new Maksutov-Newtonian from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for. The Maksutov-Newtonian design combines the best features from the Newtonian Reflector and the Maksutov-Cassegrain to create a telescope design that provides truly stunning image quality, providing high-contrast, perfectly flat images, free from false colour. The Maksutov-Newtonian design provides large aperture Apochromatic performance, with exceptional field correction, in a compact, amazingly affordable package. Stars appear as classic pinpoints across the entire field. Perfectly optimised for modern DSLR cameras. The premium optics are housed in a robust rolled-steel tube for excellent mechanical integrity. Five internal knife-edge baffles are included to eliminate internal reflections and further enhance contrast. The Primary Mirror is made of low thermal expansion Pyrex® glass for a significantly reduced cool-down time.
