A superb 9mm 6 element planetary eyepiece from TMB...
A legend in planetary observing, this high-performance 9mm planetary eyepiece offers high-powered viewing with maximum contrast. The 6-element design offers 58 degree AFOV (apparent field of view) and incorporates a Barlow lens system for ultra-high powered observing but with the large 14mm eye-relief and centering comfort you would normally only associate with a much longer focal length (and less powerful) eyepiece. And full multi-coating on all glass surfaces achieves images of the highest contrast. The eyepiece comes supplied with a large, soft, comfortable rubber eye-shield and generous 14mm eye-relief that is controlled by rotating the body. 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!
