The optics: Apochromatic refractors produce the sharpest and highest quality images of all telescope systems thanks to their shadow-free, textbook-like diffraction pattern. The Skywatcher high-end Evostar 150ED Apo refractor contains a doublet lens with a lens made of particularly low-index ED glass and a matching crown glass element. Each glass-air surface of the optics has been given an exotic, metallic anti-reflection coating to achieve a high, maximum light transmission of 99.5%! The groundbreaking Skywatcher “Metallic High-Transmission Coating” (MHC) is the highest quality optical lens coating in its class. A 0.85x reducer / corrector tailored to the telescope is also available as a special accessory. The mount: The new, computer-controlled Skywatcher EQ6-R PRO Synscan™ telescope mount is the impressive, evolutionary further development of a legend represented by the EQ6 PRO. The modern, optimized design of the EQ6-R PRO includes new equipment details that will immediately convince experienced astrophotographers: Increased payload of 20 kg for the astrophotography drive via belts for minimal “backlash” – particularly quiet and smooth operation and better results when “guiding”, as well as higher torque of the drive Improved pole height adjustment with a larger adjustment range (5° to 65°) Built-in “SNAP” camera control connection PPEC worm gear and periodic worm errors Correction function (makes this constantly new e No need to train the drive) Integrated carrying handle for easy transport The included computer-controlled Synscan™ hand control allows the telescope to be aimed at a specific object and offers tours of the current night sky with just the push of a button. The user-friendly menu system allows automatic tracking of over 42,000 astronomical objects in the night sky with its extensive database.
