You can see nearly three times the range at once compared to the standard eyepiece lens of 45 degrees to 50 degrees. You can reflect more stars than the previous eyepiece lenses, and you can see more realistic air through astronomical telescopes. In addition, although it is a super wide view type, a sharp image is secured to the surrounding area.The optimization of the internal body structure and the adoption of full multi -coating provide bright and high contrast images that suppress ghosts and flare. About eyepiece lenses and magnification ● The magnification is determined by the focal length / eyepiece lens of the objective lens lens (main mirror) of the lens barrel. For example, when an eyepiece SSW10mm (focal length 10 mm) is attached to the ED81SⅡ slender barrel (focal length 625mm), 625 ÷ 10 = 62.5 Therefore, the magnification is 62.5 times. ● Appearance of openness 83 degrees Celsius The range that can be seen all at once when looking at the eyepiece lens is called the "outlook".The outlook world is 45-50 degrees for standard eyepieces, 60-70 degrees in the wide -view type, but "SSW" achieves a super wide view of 83 degrees, far exceeding them.The spacious visibility brings an unprecedented "goodness" and "impressive". ● Sharp image spread throughout the field of view The wide -view type tends to be disturbed by the nature, but the "SSW" is designed to adopt a high -end lantern -based glass as a lens material and use a low -distributed glass, so it is sharp to the surrounding area.Connect a statue.All 4 groups of 4 groups are designed to support short -focus lares to bright F4, and you can get sharp star images. ● Abundant surrounding light amount By optimizing the position of the lens, aperture, the thickness of the tube, etc., the peripheral part of the view has been secured a 100 % light amount.You can get a complete brightness not only in the center, but also in the surrounding area where light decreasing is likely to occur. ● Bright and clear view The optimization of the internal lens structure and the high -transmit rate multi -coating ( *) on the entire lens, including the joint surface, provide a bright and extremely clear view that suppresses the generation of ghosts and flare. * Transparency over 99.5%or more in the visible light area (430-690 nm) ● Exterior design that combines beauty and practicality The body adopts a colored alumite color -coded for each focal length.It has high durability and has excellent visibility.In addition, it is equipped with a rubber protector that also has a body damage and rolling prevention, and is considered in darkness.It is an easy -to -use piece that has been developed from a user's point of view, such as a twist -up rubber view that can adjust the height by rotating the height, and a new model removal prevention groove that can be used with a ring tightening type iron adapter.""- Insert diameter size 31.7mm Visible world 83 degrees eyeleaf 13mm Weight 230g
