  • Sir Patrick Moore CBE FRS"I have used a great number of telescopes; some are good, some mediocre and some bad. To me the Sky-Watcher range of instruments are very good indeed, and suited to amateurs of all kinds – and they are not priced out of the market! Excellent value.
    Use them and enjoy them."
    Sir Patrick Moore CBE FRS (1923 to 2012)
  • Ade Ashford Says..."Having tested and reviewed a wide range of astronomical telescopes over the last couple of decades, for me there's one manufacturer that's risen above the rest in terms of delivering a coherent range of uncompromising, well-conceived designs, embodying consistently good optics and sensibly engineered mounts at very competitive prices — that's Sky-Watcher!!"Ade Ashford BScAde Ashford has tested and reviewed astronomical equipment in a professional capacity for several publications, including Sky & Telescope, Astronomy Now & BBC Sky At Night Magazine.
Dobsonian telescopes offer an incredible aperture-to-price ratio. The Dobsonian mount, popularized by John Dobson in the 1970.s, is a simple and efficient method of mounting a Newtonian reflector, based on the Alt-Azimuth principal. Fast and easy to set up, the Dobsonian mount consists of a box-type mounting which allows the telescope to pivot in altitude, while the box itself is rotated on a base in azimuth. The secret of the design is to correctly balance the optical tube and use frictional materials which allow it to be moved easily when nudged but to stay in position when not. The mount is designed to be driven by hand as opposed to slow motion controls.Sky-Watcher Dobsonians provide excellent all round performance for the observation the Moon and Planets and Deep Sky Objects such as Galaxies and Nebulae.

PARABOLIC PRIMARY MIRRORS
Features High Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal lengh reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, constrasty images, which are full of detail.
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.
