Paris, November 9, 2022 ?RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the high-performance eyepieces "smc PENTAX XW16.5" and "smc PENTAX XW23" for astronomical telescopes. This expands the XW series to ten eyepieces and rounds out the range of functional, practical focal lengths for a wide range of applications, from low magnification stargazing to high magnifi- cation planetary observation. RICOH IMAGING has a long time experience in manufacturing gear for astro observation. Beside of a product range of Spotting scopes, we are offering a wide range of Eyepieces for the use with telescopes to enjoy astro watching. Due to the increase of telescope users, demand for eyepieces is also being diversified. Out of various demand, we decided to develop new eyepieces to meet the demand of users who want to enjoy star observing with very wide FOV, which makes possible to observe astronomical objects more impressively. With the new XW series eyepieces, we increase the line-up of PENTAX eyepiece, and will en- hance PENTAX brand image as "high quality", "high performance" for Astro fans having mid to upper class telescope such as telescopes over 30cm diameter Main features of the Eyepieces smc PENTAX XW16.5 and smc PENTAX XW23 Particularly large field of view The two new eyepieces of the XW series have the largest field of view in the series at 85°. In combination with an eye relief of 20 mm, they provide a particularly wide field of view for exciting observation of nebulae and star clusters. High-quality optics for exceptional image quality The new eyepieces feature an optical system with 7 elements in 5 groups that surpasses the conventional XW series to deliver sharp star images right to the edge of the field of view. The high-performance optics consist of lanthanum glass elements with high refractive power and particularly low dispersion, which produce a balanced image with minimal aberrations. It is specially designed to reduce the annoying blackout effect by effectively compensating for the spherical aberration of the pupil. PENTAX original multi-coating for outstanding light transmission All lens surfaces that come into contact with the air are treated with the original multi-coating, while all laminated surfaces are treated with the innovative partial coating to achieve light trans- mission of more than 90 per cent (an astonishing 96 per cent at 550nm) across the visible light spectrum. Advanced light-shielding technology for improved image contrast Thanks to PENTAX's advanced computer simulation technology, the XW series features a light- shielding diaphragm in the most effective position to dramatically reduce internal reflections and provide a brighter, higher contrast image. Weatherproof construction for all-weather viewing The XW Series features a JIS Class 4* weatherproof construction that allows use even in drizzle or nighttime dew. Scope of Delivery: 16.5mm Eyepiece

Masuyama eyepieces are known for their clear and high contrast imaging and velvet black background. The good contrast of these high-end eyepieces is achieved by better grinding and internal baffles combined with the best possible internal blackening. Due to the elaborate lens design, the eyepieces get by with only 5 elements, with good correction at the same time. Despite the large field of view, the short focal length Masuyama eyepieces are fully recommended for planetary observation. At the same time, the eyepieces are of course very nice overview eyepieces for deep-sky observation. The long focal length eyepieces are well suited for finding and observing large area deep sky objects. The eyepieces were developed by renowned optician Dr. Masuyama. Among other things, Dr. Masuyama designed an eyepiece with a focal length of 100 mm, which was used on the historic 60-inch telescope at Mount Wilson Observatory in California. We are pleased to offer you these legendary eyepieces with the latest glass and coating technology. Scope of Delivery: Eyepiece Dust Caps

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
