Details

The Sky-Watcher Quattro 150P is a fast 150mm imaging Newtonian designed primarily for astrophotographers who want a compact, wide-field astrograph without sacrificing aperture. Its 600mm focal length and fast f/3.9 optical system make it well suited for imaging nebulae, galaxies and larger deep-sky targets while keeping exposure times shorter than slower optical systems.

With a 150mm aperture, 600mm focal length and fast f/3.9 focal ratio, the Quattro 150P combines the light-gathering capability of a 6-inch Newtonian with a relatively short focal length for deep-sky astrophotography. The parabolic borosilicate primary mirror uses Sky-Watcher's Radiant™ Aluminum Quartz (RAQ™) coatings, while an oversized secondary mirror is designed to provide strong illumination across camera sensors.

The included coma corrector/reducer is designed specifically for the Quattro 150P's optical system. When used for imaging, it reduces the effective focal length from 600mm to approximately 518mm and changes the focal ratio to approximately f/3.45, creating an even faster system with a wider field of view. It also corrects the off-axis coma inherent in fast Newtonian telescopes, helping produce tighter, more natural-looking stars toward the edges of the image.

Precise focus is especially important with a fast imaging system, so the Quattro 150P includes a 2-inch dual-speed Crayford-style focuser for fine focus adjustment when using astronomy cameras or DSLRs. Tube rings and a V-style dovetail plate are included for mounting the optical tube to a compatible mount.

Although optimized as an astrophotography telescope, the Quattro 150P can also be used for visual observing. The included 22mm 70° eyepiece and 6x30 finderscope allow it to provide bright, wide-field views of star clusters, nebulae and other objects. Its optical design, however, is intentionally optimized around imaging, making it particularly attractive to someone building a dedicated deep-sky astrophotography rig.

FAQ

Q: Is the Sky-Watcher Quattro 150P good for astrophotography?
A: Yes. The Quattro 150P is designed specifically with astrophotography in mind. Its 150mm aperture, 600mm focal length and fast f/3.9 focal ratio make it well suited for capturing nebulae, galaxies, star clusters and other deep-sky objects while keeping exposure times relatively short.
Q: Does the Sky-Watcher Quattro 150P need a coma corrector?
A: For astrophotography, a coma corrector is important with a fast Newtonian such as the Quattro 150P because it helps correct elongated stars toward the edges of the image. The Quattro 150P includes a dedicated coma corrector/reducer, so a separate corrector does not need to be purchased to get started.
Q: What does the included coma corrector/reducer do?
A: The included coma corrector/reducer helps correct the off-axis coma produced by a fast Newtonian optical system while also reducing the telescope's effective focal length. With the corrector/reducer installed, the Quattro 150P operates at approximately 518mm focal length and f/3.45, providing a wider field of view and an even faster imaging system.
Q: Can the Sky-Watcher Quattro 150P be used for visual astronomy?
A: Yes. Although the Quattro 150P is optimized for astrophotography, it can also be used for visual observing. Its 150mm aperture provides bright views of the Moon, planets, star clusters, nebulae and brighter galaxies. A 22mm 70° eyepiece and 6x30 finderscope are included for visual use.
Q: Is the Sky-Watcher Quattro 150P a good first astrophotography telescope?
A: It can be an excellent first dedicated imaging telescope for someone ready to learn the fundamentals of astrophotography. Its short focal length and fast focal ratio are attractive for deep-sky imaging, but as a Newtonian reflector it will require proper collimation and accurate focusing. A suitable equatorial mount is also important for successful long-exposure imaging.
Q: What mount do I need for the Sky-Watcher Quattro 150P?
A: The Quattro 150P includes tube rings and a V-style dovetail plate and can be attached to a compatible astronomical mount. For astrophotography, an equatorial mount with tracking should be selected with enough payload capacity for the telescope plus the camera, guiding equipment and other imaging accessories. The mount should be chosen based on the weight of the complete imaging system rather than the optical tube alone.
