Fits Standard 1-1/4" Diameter Focus Tubes Excellent performance and appearance Our NEW Black Knight OWL Super Plossl Eyepieces Series Our new 4 mm Super Plossl eyepiece is an excellent high power eyepiece. It will give you about a 0.21° true field and 250 power on an 8" f/5 reflector. This eyepiece has an AFOV (Apparent Field of View) of about 52°. This is an excellent eyepiece in appearance and a great performer. We believe it the equal of most any Plossl eyepiece in its focal length range regardless of the price. We also believe that our new black satin finish sets these apart from the common brands. True Plossl design eyepieces, regardless of price or brand, have an eye relief about equal to 2/3 to 3/4 of the focal length. This can be rather short with short focal length Plossls. All of our eyepieces are threaded for standard filters. They fit Meade, Orion, Celestron, OWL, and most other filters for 1.25" eyepieces. This deluxe version comes with a sturdy plastic bolt case that usually sells for $5. Contrast in very important to bring out faint deep-sky features and fine planetary detail. This eyepiece advanced multi-coated optics. The multi-coated optics on this eyepiece appear green at small angles and magenta (purple) at large angles. Multi-coating producing increased contrast and light transmission. One other fine point might be mentioned. When you tighten down the set screw on an eyepiece, you have a chance of marring the finish of the barrel. As shown in the photo, there is an indented ring on our eyepiece where the set screw fits. This allows you to use less pressure with the set screw on the eyepiece and still keep it in place. This eyepiece is a version of its type. It appears that this feature is not present on the other brands that share the same optical design. There were no compromises and a lot of thought going into the design of this eyepiece. This eyepiece fits the standard 1-1/4" (31.75 mm) eyepiece focus mount. If your telescope takes smaller eyepieces, it will not fit.
