TeleVue 4x Powermate 2″ Barlow lens

TeleVue 4x Powermate 2″ Barlow lens

If you are looking for a reliable way to significantly increase your telescope's magnification without any compromise in image quality, the TeleVue 4x Powermate 2″ is the answer. This focal multiplier stands at the very top of its category and is a trusted choice among both visual observers and astrophotographers worldwide.

Not just another Barlow lens

The Powermate is fundamentally different from conventional Barlow lenses. Its sophisticated multi-element optical system multiplies the original focal length by exactly 4x while introducing zero additional aberrations into the imaging chain. The result is a sharp, high-contrast image that remains crisp all the way to the edge of the field of view - free from vignetting and unwanted reflections thanks to TeleVue's FM anti-reflection coatings.

Compact design, wide compatibility

One of the most practical advantages of the Powermate over traditional Barlow lenses of the same magnification is its noticeably more compact body. This matters especially when working with short-tube refractors or compact Newtonians, where focus travel is limited. The shorter tube length places fewer demands on the focuser's available range.

The mechanical design has been engineered for maximum versatility:

• Standard 2″ barrel fits most focusers and star diagonals
• A 1.25″ adapter insert is included in the box, covering your entire eyepiece collection
• Soft-contact thumbscrews hold eyepieces securely without scratching barrels or coatings
• Easily adapted for direct camera attachment for astrophotography use, retaining all optical benefits of the system

Ideal for planetary observation and astrophotography

The TeleVue Powermate has earned the loyalty of planetary visual observers who demand maximum sharpness and contrast at high magnifications, as well as astrophotographers who require precise, stable optics for detailed imaging of planets and the Moon. Whether you are pushing your telescope to its resolving limit visually or capturing fine detail on a sensor, the Powermate delivers consistently.

TeleVue has been synonymous with the highest optical standards in the astronomy community for decades. The 4x Powermate is not simply a focal extender - it is an optical instrument engineered to let your telescope perform to its true potential. The investment pays for itself many times over.
