Description
Explore bright galaxies and star clusters along celestial coordinates using the Skywatcher N 150/750 Explorer 150P EQ3-2 Telescope manual German equatorial reflector system. Designed with a fast f/5.0 focal ratio, this 150mm (5.91 in) aperture telescope features a 750mm focal length, delivering 0.77 arcseconds Dawes resolving power and reaching magnitude 13.6 for deep-sky scanning and lunar observation.
The Skywatcher N 150/750 Explorer 150P EQ3-2 Telescope features a precision parabolic primary mirror made from low-expansion borosilicate optical glass, coated with 94% reflective aluminum and a protective silicon dioxide (SiO2) layer. Its 673mm solid metal tube incorporates a 42mm secondary mirror (28% obstruction by diameter) and a 1.25-inch rack-and-pinion focuser. Mounted on an EQ3-2 manual German equatorial mount on an aluminum tripod, the 4.93 kg (10.87 lbs) OTA ensures steady polar tracking.
Key Features of Skywatcher N 150/750 Explorer 150P EQ3-2 Telescope
Built for manual equatorial deep-sky scanning, lunar surface observation, and bright galaxy hunting, this 150mm Sky-Watcher Explorer Black Diamond telescope pairs fast f/5.0 parabolic optics with an EQ3-2 mount. Its dual slow-motion controls and 2x Barlow lens deliver versatile visual performance.
- 150mm (5.91 in) clear aperture with 750mm focal length and fast f/5.0 optical speed
- Precision parabolic primary mirror made from low-expansion borosilicate glass
- 94% reflective aluminum optical coatings with protective silicon dioxide overcoat
- 28% secondary mirror obstruction by diameter (42mm minor axis, 7.8% by area)
- 1.25-inch single-speed rack-and-pinion focuser for smooth focus adjustments
- EQ3-2 manual German equatorial mount with dual slow-motion control cables
- Adjustable aluminum tripod with integrated central accessory storage tray
- 6×30 optical finderscope, 2x Barlow lens, and Super 25mm and 10mm eyepieces included
Fast f/5.0 Parabolic Optics & Low Spherical Aberration
The 150mm parabolic primary mirror focuses light accurately to eliminate spherical aberration, delivering bright, wide-angle views of open star clusters and nebulae. Supported by a 1.25-inch focuser, this Sky-Watcher reflector supports visual magnifications from 21.4x up to 300x.
EQ3-2 German Equatorial Mount & Dual Slow-Motion Controls
Tracking celestial objects at high magnification requires steady, vibration-damped mechanics under open skies. The Sky-Watcher Explorer 150P includes an EQ3-2 equatorial mount with dual slow-motion cables, allowing observers to track objects along right ascension and declination smoothly. Supported by an aluminum tripod, it provides a stable viewing platform for deep-sky observation and lunar viewing.
- EQ3-2 manual German equatorial mount with dual-axis slow-motion control cables
- Sturdy aluminum tripod column with central accessory tray for maximum dampening
- Included 2x Barlow lens doubling visual magnification across both included eyepieces
Sky-Watcher Explorer Black Diamond Warranty
The Skywatcher N 150/750 Explorer 150P EQ3-2 Telescope is backed by a 2-year limited warranty against material and manufacturing defects. The complete factory package contains the 150mm parabolic OTA, EQ3-2 mount head, aluminum tripod with tray, counterweights, 6×30 finderscope, Super 25mm and 10mm eyepieces, and a 2x Barlow lens.
