Correct the coma

A fast Newtonian flares stars at the edge of frame. This fixes it.

Set it up right

A Newtonian needs collimating and the optics need keeping clean. Both jobs come up on night one.

Dew protection

A Newtonian dews on the secondary mirror, not the front. This heats it directly.
  • Description
  • Specifications
The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. A 2" dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography. Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector.

  • 205 mm Newtonian reflector
  • 800 mm (f/4)
  • Fully multi-coated borosilicate mirrors
  • 2” dual-speed 10:1 linear power focuser
  • 8×50 finderscope
  • Tube rings with V-style dovetail bar
