Sky-Watcher Quattro-200P: Eight Inches Full Speed
The Sky-Watcher Quattro-200P is a 205/800mm f/4 astrograph with low-expansion borosilicate primary and secondary mirrors. Eight inches of aperture that collects the same signal in half the time of an f/8 system: the all-around size among fast imaging Newtonians.
What can you photograph with it?
Everything where signal counts: faint nebulae, vast H-alpha regions, galaxies, and dust lanes. Where a slower system integrates for hours, an f/4 system captures the same on the sensor in half the time. Visually (with its own eyepieces), it is also a bright deep-sky telescope with a surprisingly sharp image in the center.
Why a Quattro?
The Quattro line is Sky-Watcher's fastest Newtonian series: f/4 means four times as much signal per minute as an f/8 system. The dual-speed Linear Power focuser (10:1) carries cameras without sagging and focuses at the pixel level. Note the fair caveat: no eyepiece is included. This is an astrograph; visual use is entirely possible, but with your own eyepieces.
This is how to get the most out of this telescope
- Collimation at f/4 is surgical work: check for every session with a good collimator. Our guide to collimation describes the routine.
- The aplanatic corrector belongs with it: Without a corrector, f/4 stars are comet-shaped at the edge. Factor this into the purchase, not afterwards.
- Mounting choice: Consider the EQ6-class mount; the 9 kg tube with camera and corrector requires a counterweight.
- Guiding the moon At this brightness, every arcsecond of pointing accuracy counts in the star points.
- Give the mirror some cooling time and consider a light shroud against stray light and dew.
- Visual assistance a 6 mm eyepiece It magnifies 133x; but bring your own eyepieces, there are none in the box.
For whom yes and for whom no
Hello The advanced photographer who wants resolution and speed in one package.
Not If you want photo results without mounting, guiding, and post-processing, then the smart telescopes the shorter route; ours Telescope Buying Guide for Beginners explain the trade-off.
Featured accessories
These accessories add the most after purchase:
- Aplanatic coma corrector f/4 at f/4, a corrector is not an option but a part of the optical system. The Sky-Watcher 2 inch Aplanatic Coma Corrector is specifically designed for the Quattro line and is a standard component.
- Cheshire eyepiece the Sky-Watcher Cheshire Eyepiece makes the critical f/4 collimation accurate and repeatable.
- Light Pollution Filter (2 inch) gets merk more contrast out of your shots under Dutch or Belgian skies.
- Moon Filter 13%: with this opening, the moon is blindingly bright; the Omegon Moon Filter 13% (1.25 inches) The light fades. More explanation in our Moon filter guide.
