Sky-Watcher Quattro 200 f/4 Imaging Newtonian

Sky-Watcher Quattro 200 f/4 Imaging Newtonian

DESCRIPTION

The Sky-Watcher Quattro 200 f/4 is an imaging-optimized Newtonian reflector. Its 205 mm parabolic primary mirror, made of low expansion glass, ensures rapid thermal equilibrium and stable focus. With an 800 mm focal length and fast f/4 ratio, it’s ideal for capturing wide deep-sky targets in shorter exposures.

The steel optical tube includes nine internal baffle rings that suppress stray light and reinforce structural rigidity. The ultra-thin 0.5 mm secondary mirror supports reduce obstruction and enhance image brightness.

Focusing is handled by a 2" linear Crayford dual-speed focuser (10:1). Instead of gears, it uses rollers for smooth, backlash-free operation. It includes a 2" drawtube with an integrated male T-thread for secure camera connection with the proper T-ring. A 9x50 finderscope, tube rings and a Vixen-style dovetail bar are included.

Eyepieces are not supplied, giving users the flexibility to choose their optical setup and corrector depending on their camera's sensor.
