Sky-Watcher N 150/750 OTAW Newtonian Reflector Telescope
Important! Optical tube assembly only with accessories.
High-Quality Newtonian Reflector for Deep-Sky Exploration
The Sky-Watcher N 150/750 OTAW represents a premium **Newtonian reflector telescope** featuring a 150mm primary mirror diameter and 750mm focal length. This telescope utilizes the proven Newton optical design with f/5 optics, ensuring exceptional light-gathering capability perfect for observing faint deep-sky objects including nebulae, galaxies, and star clusters. The parabolized primary mirror guarantees sharp imaging without spherical aberration across the entire field of view.
Exceptional Light-Gathering Power
The six-inch aperture diameter provides 460 times more light than the human eye, enabling observation of objects up to 13th magnitude. The short 750mm focal length combined with f/5 optics makes this telescope an ideal instrument for astrophotography and observation of extended celestial objects. The high-quality **parabolic mirror** is precisely ground to deliver contrasting and detailed images with minimal optical aberrations.
Advanced Focuser System
The telescope features a modern Crayford-type focuser with 2″ output, allowing use of both standard 1.25″ eyepieces via the included reducer and larger 2″ eyepieces and accessories. The 6x30 finder scope provides a wide field of view for easy targeting of observed objects.
Complete Optical Package
The standard equipment includes eyepieces providing 30x and 75x magnification, covering a wide spectrum of observational possibilities from wide-field viewing to detailed object study. The package includes:
- 150mm f/5 parabolic primary mirror
- Crayford focuser with 2″ drawtube
- 1.25″ eyepiece adapter
- 6x30 finder scope
- Two eyepieces (30x and 75x magnification)
- Tube rings and mounting rail
Universal Mounting Compatibility
The delivery includes mounting rings and a Vixen/Celestron standard mounting rail, ensuring compatibility with most available equatorial mounts. The total package weight is 8.5 kg, reflecting solid construction while maintaining reasonable weight for portable observation.
