150 mm parabolic Newtonian telescope with 750 mm focal length and f/5 focal ratio. The Sky-Watcher Explorer 150P combines versatile optics, high-reflectivity RAQ coatings, a 6 × 30 finder, two eyepieces and a 2× Barlow lens.
Designed as a versatile telescope for astronomical observation, the Sky-Watcher Explorer 150P uses a 150 mm Newtonian optical system with a 750 mm focal length and f/5 focal ratio.
Its parabolic primary mirror provides strong performance on the Moon and planets as well as many deep-sky objects including nebulae, galaxies and star clusters.
The 150 mm primary mirror features a parabolic surface.
This geometry brings incoming light rays to the same focal point and avoids the spherical aberration associated with spherical mirrors used at short focal ratios.
With its 150 mm aperture, the Explorer 150P gathers sufficient light for observing a wide range of astronomical objects.
With a 750 mm focal length and 150 mm aperture, the Explorer 150P operates at f/5.
This configuration provides a useful balance between field of view, image brightness and the ability to reach higher magnifications with suitable eyepieces.
The primary and secondary mirrors feature Sky-Watcher Radiant Aluminum Quartz RAQ coatings.
The coating combines reflective aluminium, a dielectric tantalum pentoxide layer designed to improve reflectivity and durability, and a protective silicon dioxide layer.
Sky-Watcher specifies reflectivity of up to 94%.
The secondary mirror is supported by four 0.5 mm thin spider vanes.
This design minimises obstruction of the optical path and helps reduce diffraction spikes.
With its 750 mm focal length, the Explorer 150P is suitable for observing lunar surface detail and the major bright planets.
Sky-Watcher specifies a highest practical power of 300× when atmospheric conditions and the optical configuration allow.
Its 150 mm aperture and f/5 focal ratio also make the telescope suitable for observing many deep-sky objects.
Nebulae, galaxies and star clusters are among the principal targets accessible with this instrument.
Two eyepieces are supplied with the telescope.
The 20 mm eyepiece provides 37.5× magnification while the 10 mm eyepiece provides 75×.
A 2× 1.25-inch Barlow lens is included.
Combined with the supplied eyepieces, it provides additional magnification options, including 150× with the 10 mm eyepiece.
A 6 × 30 optical finderscope is supplied to assist with locating and centring celestial objects before observing through the main telescope.
A universal smartphone camera adapter is included.
It supports smartphones between 54 and 90 mm wide and allows the phone camera to be positioned behind the eyepiece for image capture.
The Explorer 150P also supports direct connection to a compatible DSLR camera.
This provides an additional imaging option alongside the supplied smartphone adapter.
