PRO-SERIES is the name for the new generation of professional quality telescopes and mounts of the Sky-Watcher range, targeted at the most discerning and critical observers.
PRO-SERIES products are manufactured to extremely high levels of optical and mechanical precision, undergoing very strict quality control procedures and testing by specially assigned technicians, to ensure the highest standards of quality and performance are consistently maintained.
─__Great package for the price─__The telescope optics are fully multicoated and the secondary mirror obstructs just 26 per cent of the primary diameter, making it good for planetary imaging. Testing the optics showed excellent correction and contrast; results that were backed up by our observations of a variety of celestial objects. Views of Saturn during a night of superb seeing were excellent - we could clearly see the Cassini Division in the rings and the planet's equatorial band. Contrast on the Moon was very high and it split the stars of the ─__Double-Double' very cleanly."

SKY-WATCHER DELUXE MIRROR COATINGS
Most reflectors today usually have a coat of aluminium as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is therefore more expensive. Protection is needed, because in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope.ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.
