Description
Capture ultra-fast wide-field deep-sky exposures across extended emission nebulae with the Skywatcher N 150/600 Quattro-150P OTA imaging astrograph reflector telescope. Operating at f/4.0 or an accelerated f/3.45 with its included 4-element coma corrector, this 150mm (5.91 in) aperture instrument delivers 0.77 arcseconds Dawes resolving power and reaches magnitude 13.6 for high-speed astrography.
The Skywatcher N 150/600 Quattro-150P OTA features a borosilicate parabolic primary mirror coated with 94% reflective dielectric enhanced aluminum and silicon dioxide. Its 550mm steel tube incorporates an enlarged 51mm secondary mirror and a dedicated 4-element 0.86x coma corrector containing FPL-51 glass. Equipped with a 2-inch Linear Power Track Crayford focuser with 1:10 micro-reduction and a 360-degree rotator, this 5.70 kg (12.57 lbs) OTA yields a flat 44mm full-frame circle.
Key Features of Skywatcher N 150/600 Quattro-150P OTA
Engineered for high-speed wide-field deep-sky astrophotography, this 150mm Sky-Watcher Quattro astrograph pairs fast parabolic optics with an included 4-element 0.86x coma corrector. Its rotatable 2-inch Linear Power focuser and standard 55mm backfocus deliver pinpoint, flat-field star profiles across full-frame sensors.
- 150mm (5.91 in) aperture with 600mm focal length and fast f/4.0 optical speed
- Accelerates to 518mm focal length at ultra-fast f/3.45 with included 0.86x reducer
- Dedicated 4-element super coma corrector containing FPL-51 optical glass element
- Corrected 44mm full-frame image circle with standard 55mm M48 back focus
- Enlarged 51mm secondary mirror obstruction (34% diameter, 11.6% area) for full illumination
- 2-inch dual-speed Linear Power Track Crayford focuser with 1:10 micro-drive and 360° rotation
- Vixen-style 44mm dovetail bar with cast-aluminum tube rings and 6×30 finderscope included
Fast f/3.45 Reduced Optics & 44mm Full-Frame Field
The included 4-element optical coma corrector eliminates off-axis coma while shortening focal length to 518mm at f/3.45, reducing sub-exposure times drastically. Supporting visual and photographic magnifications from 21.4x up to 300x, this Sky-Watcher Quattro astrograph delivers flat-field sharpness out to the corners of full-frame sensors.
2-Inch Linear Power Track Focuser & 360° Field Rotator
Heavy camera trains require an unyielding mechanical drawtube to prevent sensor tilt during exposures. The Quattro-150P features a 2-inch Linear Power Track focuser reinforced with a stainless steel drive rail and a 1:10 micro-focus reduction knob. Its integrated 360-degree rotation collar enables effortless image framing without loosening the cast-aluminum tube mounting rings.
- 2-inch dual-speed Linear Power Track Crayford focuser with 1:10 planetary micro-drive
- Built-in 360-degree field rotator for seamless astrophotography composition
- Standard M48x0.75 male connection thread on corrector with 55mm flange distance
Sky-Watcher Quattro Series Warranty
The Skywatcher N 150/600 Quattro-150P OTA is backed by a 2-year limited warranty against material and manufacturing defects. The complete factory package contains the 150/600 Quattro OTA, dedicated 4-element coma corrector and reducer, cast-aluminum tube rings, Vixen-style dovetail bar, 6×30 finderscope, and a 2-inch to 1.25-inch reduction adapter.
