Ricoh Imaging Americas Corporation today announced two high-performance eyepieces for astronomical telescopes. The new smc PENTAX XW16.5 and smc PENTAX XW23 deliver an apparent field of view of 85° — the widest viewing angle in the XW series, suitable for observing nebulae and star clusters.
The new eyepieces feature a new optical system with 7 elements in 5 groups that surpasses the performance of the conventional XW series to obtain sharp star images all the way to the edge of the field of view. Like all XW eyepieces, the new additions incorporate multi-layer coating for outstanding light transmission efficiency, advanced light-shielding technology for improved image contrast and weather-resistant construction. (Note: while the XW series features a weather-resistant structure of JIS class 4, they cannot be used underwater.)
