Takahashi 2X Ortho Barlow Lens 

Have you ever longed to push your observation power further without sacrificing image quality? The new 2x Ortho Barlow shatters the stereotype of barlow lenses degrading clarity. It takes exploration to a whole new level, extending focal length with zero added aberrations, thanks to its innovative design paired with your existing aberration-free objective lens.

Introducing the Ortho of a new era:

• Unprecedented Sharpness: This barlow doesn t just magnify, it amplifies your view. Witness stunning central and peripheral details, exceeding even the expectations of our highly anticipated TPL series eyepiece.

• Airy Disks Across the Field: Gone are the days of compromised edges. In conjunction with the TOA tube and TPL-6mm eyepiece, even the slightest peripheral imperfections vanish, revealing star images within the Airy disk across the entire field.

• Chromatic Aberration? Not Here: Bid farewell to color fringing. The 2x Ortho Barlow cancels out the TOA s subtle chromatic aberration, delivering pure, clear star points.

• Versatility Redefined: Beyond 31.7mm sleeves, an M42 P0.75 T-ring screw expands your horizons, welcoming other attachments for diverse imaging needs.

• Photographic Prowess: Forget the past. This barlow surpasses its predecessor in both central image chromatic aberration and peripheral coma, ensuring exceptional astrophotography results.

• Seamless Switching: Experience smooth transitions. The parfocal design maintains focus even with the barlow in play.

• Compact and Convenient: For effortless zenith mirror usage, this short barlow comes with a 31.7AD adapter, letting you double your magnification on the fly.

• The magnification ratio of the Takahashi Ortho 2x Barlow lens varies as a function of the distance to the lens to the formula m = 2 + 0.0121 x b, where m is the magnification and b is the distance between the end of the T thread and the surface of the sensor (or entrance diaphragm in the case of an eyepiece).

  For a ZWO planetary camera with a backfocus length of 17.5 mm, the value of b is 12.5 mm (the T-thread is 5 mm long). So, according to the formula above, the magnification is 2.15.

  The 2x Ortho Barlow is more than just a lens; it s a gateway to a world of uncompromised astronomical clarity. Dive deeper into the cosmos, rediscover the thrill of seeing farther, and witness stars like never before.
