Sky-Watcher STARGATE Dobsonians with their huge light gathering capabilities
provide the ultimate WOW factor experience for aficionados of visual
astronomy, delivering outstanding performance on both Planetary and Deep-Sky
objects.  The elegant and rigid all metal truss tube design is easily
transportable when unassembled, and can be assembled and ready for use in
about 20 minutes. The mount provides motorised operation in both Alt and
Azimuth axes, and can slew the telescope automatically to, and track over
42,900 night sky objects from the Synscan handset's extensive computerised
database. Features Freedom-Find™ Dual-Encoder technology, which also allows
the telescope to be moved manually in either axis without losing it's
alignment or positional information, giving the user enormous convenience and
flexibility during observing sessions. Simply push the telescope close to the
object and let the computer do the rest of the work!

The Mirror

The STARGATE-450P SYNSCAN 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.

The 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.
