• For twenty years Sky-Watcher has been bringing the astronomy market quality products at value prices. To celebrate, Sky-Watchter teamed up with Starlight Xpress to offer limited-edition astrograph packages. By matching their award-winning astrographs with the Trius SX-42 camera, Sky-Watcher and Starlight Xpress eliminated all of the headaches associated with configuring an imaging train. Back focus, adapters, guiders, filter wheel, etc. are all taken care of. Simply attach these kits to your favorite mount, plug into a computer, add your filters and you’re ready to go.

  Quatrro 300 OTA Features

  Fast f/4 focal Ratio

  This is especially important for astrophotographers dealing with long exposure times. Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. It can remain in focus for a longer period of time and long exposure images will stay clear and in focus. Tube interiors are equipped with knife-edge ray traced baffles.

  2-Inch Dual-Speed Focuser

  The linear power focuser utilizes 4 precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Moving the drawtube by the roller rather than a rack and pinion ensures exceptionally smooth operation and precise adjustability. The dual-speed feature has a second focus knob that has a 10:1-speed reduction to provide the super-fine adjustments even the most demanding users can appreciate.

  High-Quality Mirror

  It features paraboloidal primary mirrors made of Low-Expansion Borosilicate Glass resulting in substantially shorter cooling-down times.

  It comes with an impressive 0.5 mm Ultra-Thin Secondary Mirror Support and it is 77% more Light-Gathering than 150mm.
