This is the original, not a clone - the legendary true TMB 7mm planetary eyepiece.  It is in excellent condition, with clean optics and unmarked body.  It does not have any dust caps or a box.  


  • Designed primarily for planetary observation but great for deep sky objects too
  • Wide 58 degree Field of View (FOV) in 2.5mm to 25mm focal lengths
  • Comfortable eye relief averaging 16mm across the series
  • Exceptional at nearly eliminating lateral color aberration and light scatter while retaining excellent sharpness, contrast and definition
  • Modified Plossl design with five lenses in three groups (except for the 20mm which has four groups)
  • In field use, perform as well as other, more expensive Orthoscopic and Plossl eyepieces
  • Excellent fit and finish with fully multicoated lenses and flat black anodized internal baffles and field stop

A legend in planetary observing, this high-performance 7mm planetary eyepiece offers high-powered viewing with maximum contrast. And full multi-coating on all glass surfaces achieves images of the highest contrast.  The amazing 58 degree AFOV (apparent field of view) design will perform well with virtually all modern telescopes.

This is a truly outstanding eyepiece that will deliver the best planetary views your telescope is capable of!

The quality of construction is everything you would expect from a TMB premium-quality eyepiece - all metal-engraved body and barrel (which is of course threaded for standard filters).

One of the worlds finest planetary eyepieces at a stunning low-price!
