  • Sky-Watcher Quattro 150P Imaging Newtonian 6" (150mm)

    The Sky-Watcher Quattro 150P is a 150mm (6") imaging Newtonian with a 600mm focal length and a paraboloidal primary mirror. With the included coma corrector/reducer it works at 518mm and f/3.45 and attaches to the camera by M48 thread. The 5.7 kg (12.6 lb) tube comes with a 2-inch dual-speed 10:1 Crayford focuser, a 6x30 finderscope and a 22mm eyepiece.

    The Quattro 150P: f/3.9 Native, f/3.45 with the Corrector

    The Quattro 150P is f/3.9 natively and works at f/3.45 with the included coma corrector/reducer, and the fast focal ratio is especially important for astrophotographers working with long exposures.

    150mm Paraboloidal Mirror and 64mm Secondary

    The paraboloidal primary mirror is made of low-expansion borosilicate glass, which gives substantially shorter cool-down times.

    The secondary mirror is 64mm in diameter and sits on a 0.5 mm ultra-thin support, which greatly improves light gathering.

    • Primary mirror: 150mm paraboloidal, 600mm focal length (f/3.9).
    • Secondary mirror: 64mm.

    Focus Stability

    Imaging telescopes made of less thermally stable material can drift from best focus during long exposures; the Quattro stays in focus for longer, keeping long-exposure images sharp.

    Coma Corrector/Reducer

    The included coma corrector/reducer gives 518mm at f/3.45 and connects to the camera by M48 thread.

    2-inch Dual-Speed 10:1 Crayford Power Focuser

    Four precision ball bearings support the drawtube, which gives stability and zero image shift with a heavy eyepiece or camera.

    A roller moves the drawtube instead of a rack and pinion, for smooth operation and precise adjustment, and a second knob with a 10:1 reduction gives super-fine adjustments.

    A 5.7 kg Tube With Rings, Finder and Eyepiece

    The tube weighs 5.7 kg (12.6 lb), is 22" long and 7.25" in outer diameter, and comes with tube rings on a V-style dovetail plate.

    A 6x30 finderscope, a 22mm 70° ultra wide 1.25" eyepiece (27x) and 2" and 1.25" compression-ring eyepiece adapters are included. The highest practical power is 300x.

  • Is the included coma corrector needed for imaging?

    It is included so you can image straight away: with it, the Quattro 150P works at 518mm and f/3.45 and connects to the camera by M48 thread.

    What kind of mount do I need for the Sky-Watcher Quattro 150P?

    The tube weighs 5.7 kg (12.6 lb) and comes with tube rings on a V-style dovetail plate, so choose a mount with a Vixen-style saddle and a payload rating that covers the tube plus your camera and accessories.

    Can I use it visually?

    A 22mm 70° ultra wide eyepiece and a 6x30 finderscope are included, and the highest practical power is 300x.

    How large is the secondary mirror?

    64mm in diameter, on a 0.5 mm ultra-thin secondary support.

    What is a dual-speed 10:1 Crayford focuser?

    A Crayford focuser whose drawtube rides on four precision ball bearings and is moved by a roller rather than a rack and pinion. The second knob has a 10:1 reduction for super-fine adjustment; it holds a heavy eyepiece or camera with zero image shift.

    What is the primary mirror of the Quattro 150P made from?

    Low-expansion borosilicate glass, figured as a paraboloid. This gives substantially shorter cool-down times.

    How do I attach my DSLR camera to the Quattro 150P?

    The included coma corrector/reducer has an M48 camera thread, so use an M48 adapter for your camera.

    What are the native and corrected focal lengths of the Quattro 150P?

    600mm natively (f/3.9) and 518mm at f/3.45 with the included coma corrector/reducer.

    Does it stay in focus during long exposures?

    The Quattro stays in focus for longer than imaging telescopes made of less thermally stable material, keeping long-exposure images sharp.

    What eyepiece adapters come with the Quattro 150P?

    A 2" eyepiece adapter and a 1.25" eyepiece adapter, both with compression rings.

    What magnification does the included eyepiece give?

    27x with the 22mm 70° ultra wide eyepiece.
