Sky-Watcher Nomad-5 1.25" Telecentric Barlow Lens

Sky-Watcher NOMAD-5 1.25" 5x Telecentric Barlow Lens

The Sky-Watcher NOMAD-5 1.25" 5x is a telecentric focal length extender designed for demanding visual observations and astrophotography. Its five-element optical construction, high-refractive-index optical glass and fully multi-coated anti-reflection surfaces provide good light transmission and high image sharpness while helping reduce the risk of chromatic aberration.

Key advantages

• 5x magnification factor, increasing the effective focal length of the telescope fivefold.
• Telecentric optical design for visual observing and astrophotography.
• High-refractive-index optical glass.
• Fully multi-coated FMC optics.
• Blackened lens edges and internally threaded anti-reflection surfaces.
• Compatible with 1.25" eyepieces and accessories.
• Self-centering brass compression ring for secure accessory retention and protection against scratches.
• Metal housing and secured locking screws to reduce the risk of accessories accidentally falling out.
• 1.25" filter thread and a safety undercut on the barrel.
• DSLR M48 and CCD adapters included.
• Weight: 190 g without accessories.

Product description

The Sky-Watcher NOMAD-5 increases the effective focal length of a telescope by a factor of five, delivering higher magnification with the eyepiece in use. This makes it possible to observe the Moon, planets and other bright Solar System objects in greater detail while using comfortable long-focal-length eyepieces of 20 mm and longer.

Its telecentric design makes it suitable for use with both fast Newtonian telescopes and apochromatic refractors, maintaining good field correction and image quality.

For astrophotography, the NOMAD-5 allows a larger image scale without a pronounced loss of the telescope's optical quality. It is particularly recommended for planetary imaging and high-resolution lunar surface photography. The optical system helps maintain neutral colour rendition and good field correction when used with astronomical cameras.

Note: the source description specifies both a five-element optical construction and a four-element lens system. These details conflict, so the exact element count should be verified against the manufacturer's specifications for the particular version.

The self-centering brass compression ring securely holds eyepieces and other accessories while protecting their barrels from scratches. The metal housing provides a durable construction, and the secured locking screws reduce the risk of accidental disconnection. The 1.25" barrel features a filter thread and a safety undercut for more secure retention in the telescope focuser.

Connecting a DSLR camera requires a camera-specific M48x0.75 adapter ring. DSLR M48 and CCD adapters are included.
