Operating Instructions Meade® Series 6000™ ED APO Refractor Optical Tubes Fig. 1: 115mm ED APO OTA with 2" Series 6000 enhanced diagonal shown. Introduction The Meade Series 6000 ED APO are true three-element apochromatic refractors that are virtually free of chromatic aberration (color fringing), providing pinpoint star images. A Series 6000 ED APO is the ideal companion for your larger Advanced Coma-Free, Schmidt-Cassegrain, or Newtonian scope. When piggybacked, a Series 6000 ED APO is the ideal wide-field photography scope when guided by the primary instrument and doubles as a guide scope for the primary telescope. It also makes an ideal lightweight and portable scope for flawless visual observing. Features • FAST FOCAL RATIO: At f/6 (80mm), f/7 (115mm) and f/7 (130mm), the focal ratio of these scopes is ideal for wide field astrophotography. • PREMIUM ED GLASS: Meade uses premium Extremely Low Dispersion glass. This glass is created to achieve a very small change in refractive index with different wavelengths of light. This makes it the perfect choice for a fast, high performance optical design like the Meade Series 6000 ED APOs. • FULLY MULTI-COATED LENSES: Meade broadband fully multicoated lenses ensure maximum light transmission. • TRUE ED APOCHROMATIC TRIPLET: A true triplet optical design guarantees the textbook color correction you expect from a premium APO. • DEW SHIELD/SUN SHADE: An essential accessory builtin to the design for your convenience. • MACHINED ALUMINUM DUAL SPEED CRAYFORD STYLE FOCUSER: Superior focuser means smooth and repeatable focusing with no image shift. Fine and super fine focusing speeds. Accepts 1.25" & 2" accessories. • 80mm FEATURES A LARGE 2" DIAMETER FOCUSER, THE 115MM AND 130MM FEATURE A LARGER 30MM FOCUSER: Allows usage of a wide range of accessories. • PRECISION, EASY TO READ FOCUS SCALE ON FOCUSER DRAW TUBE: Easily repeat critical focus points. • CRADLE RINGS AND MOUNTING BRACKET: Allows mounting on a wide variety of Meade and non-Meade German Equatorial Mounts and most photo tripods. Using the Focuser Assembly Insert an eyepiece into the focuser assembly and tighten the focuser thumbscrew. To focus the telescope, turn the fine focuser wheels in or out. If you have a 2 inch eyepiece, remove the 1.25" eyepiece holder from the focuser assembly by loosening the holder thumbscrew. Slide the 2 inch eyepiece into the holder and tighten with the eyepiece locking screw. The focuser has a locking knob. That knob locks the focuser, thereby locking the focus position into place.
