## Summary description

Tele Vue Big Barlow Lens 2x, 2-inch barrel, provides a fixed 2× increase in focal length for compatible eyepieces. Designed for use with telescopes that accept 2" accessories, it doubles magnification while maintaining image quality. Useful for planetary and lunar observations, high-magnification views, and extending eyepiece range without changing eyepieces.

## Long description

The Tele Vue Big Barlow Lens 2x with a 2" barrel increases the effective focal length of compatible eyepieces by a fixed factor of two. It is designed for telescopes that accept 2" accessories and provides a straightforward way to double magnification without changing eyepieces. The optical design maintains image quality across the field, making it suitable for higher-power views where detail is important.
Advantages
This 2× Barlow lens delivers a stable, predictable increase in magnification while preserving contrast and sharpness. The 2" barrel format provides secure mechanical fit and compatibility with common 2" focuser systems and accessories. Its fixed magnification factor simplifies imaging and visual observing workflows, and it avoids the need to purchase additional high-power eyepieces to achieve greater magnification.
Suitable for
Planetary and lunar observation requiring increased magnification
High-magnification visual viewing of double stars and planetary detail
Extending the usable range of existing eyepieces without changing oculars
Astrophotography where a simple, fixed focal length multiplier is needed
Key specifications
Magnification factor: 2× fixed
Barrel diameter: 2 inches (standard 2" accessory size)
Optical purpose: increases telescope effective focal length for eyepieces
Compatibility: designed for telescopes and focusers that accept 2" accessories
Application: visual observing and compatible imaging uses
How to use
Insert the Tele Vue Big Barlow Lens into the telescope focuser and secure it as you would any 2" accessory, then insert the eyepiece into the Barlow's eyepiece socket. Focus the telescope normally; the Barlow effectively doubles the focal length seen by the eyepiece, so fine focus adjustments may be required. For imaging, mount the camera or adapter in place of a visual eyepiece following the same procedure. Ensure all connections are tightened to avoid image shift during focusing.
Usage recommendations
Use the Barlow with eyepieces that perform well at higher focal ratios to maintain image sharpness. For the best results on planets and the Moon, pair with high-quality, medium- to high-power eyepieces and allow the telescope to reach thermal equilibrium before attempting detailed observations.
