Sky-Watcher Quattro-150P: de lichtste f/4-astrograaf
De Sky-Watcher Quattro-150P is een ultralichte 150/600 mm Newton op f/4: maximaal signaal per minuut in een buis van maar 5,7 kg. Daarmee is dit de enige serieuze f/4-astrograaf die nog op een HEQ5-klasse montering thuishoort, en de snelste route naar diepe opnames zonder zware apparatuur.
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 Newton series: f/4 means four times as much signal per minute as an f/8 system. The dual-speed Linear Power focuser (10:1) holds cameras without sagging and focuses at the pixel level. Note the honest disclaimer: no eyepiece is included. This is an astrograph; visual use is excellent, 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: een HEQ5-klasse montering draagt deze lichte buis met camera en guiding comfortabel.
- 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 geeft 100x; breng dan wel je eigen oculairs mee, er zit er geen in de doos.
For whom yes and for whom no
Hello de astrofotograaf die snelheid en mobiliteit combineert, en de HEQ5-bezitter die het maximale uit zijn montering wil.
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 25%: for visual moon phases dims the Omegon Moon Filter 25% (1.25 inches) the bright light. More explanation in our Moon filter guide.
- Carrier bag de 150/750-tas biedt deze korte buis ruim plek. Bekijk de carrier bags.
