A Valuable Addition to Your Astro Toolkit!

Get closer to the beauty of the universe than ever before! Increasing the magnification of your eyepieces broadens your viewing opportunities, making it an essential tool for stargazing. Read on as we take a deep dive into the aspects of this Apertura 2.5x Barlow lens below.

Apochromatic Optics
Housed with three optical elements, this Barlow lens effectively corrects for chromatic aberration, delivering beautiful, color-accurate sights. This makes it particularly useful when viewing bright objects like the Moon or the planets where color fringing is most apparent. Additionally, the apochromatic design offers use with eyepieces of higher quality, broadening your eyepiece compatibility range! Each lens element is fully multi-coated for maximum light throughput, ensuring the utmost clarity and detail.

2.5x Magnification
By increasing your magnification by 2.5x, the target you’re viewing is much larger within your eyepiece, making it easier to see existing details. This is especially useful for revealing planetary details such as the surface of Mars, the Cassini Division on Saturn, and Jupiter’s Great Red Spot. Barlow lenses also work wonders for the splitting of double stars, enhanced sights of the Moon’s craters, and can even help discern details on bright nebulae.

Durable Construction
This Apertura 2.5x Barlow Lens accepts 1.25” eyepieces making it useful with a wide variety of eyepieces on the market today. It can also be used with 1.25” filters for expanded viewing opportunities! The barrel length comes in at a rated 29.46 mm, with a total unit length of 77.62 mm. The outer diameter of the eyepiece holder is 40.99 mm. An included thumb screw makes docking your eyepieces a breeze and holds them in place all night long with a non-marring compression ring. For secure handling in the dark or when wearing gloves, the exterior of this Barlow lens features a rugged rubber grip.

Comes with the Apertura Absolute Warranty
The Apertura Absolute Warranty provides two years of coverage against product defects. After the initial two-year warranty expires, this product qualifies for Apertura's Three-Year Accident Replacement Program. In addition, the Apertura Absolute Warranty is transferable! Download a copy of the Apertura Absolute Warranty for more information on this program, how to make a claim, and why it is important to keep your original receipt and the product's original boxes and packaging!
