Meade 80mm Series 5000 ED APO Optical Tube Assembly

 

 

The Series 5000 80 mm Triplet ED APO OTA from Meade is a 3-element apochromatic refractor telescope with an aperture of 3.1" and a focal length of 480 mm. It's designed to deliver crisp wide-field viewing capability, and outstanding astrophotography performance.

Featuring a triple objective lens manufactured from high-quality ED (extra-low dispersion) glass, the Series 5000 ED APO virtually eliminates all chromatic aberration. The absence of color fringing allows for textbook-perfect pinpoint star images - with the Series 5000 ED APO, deep-sky observers can depend on stunning high-resolution viewing.

The Series 5000 ED APO OTA comes fitted with a 2.0" Crayford focuser and a Series 5000 2.0" diagonal. The manual dual-speed focusing unit offers a 10:1 gear-reduction for ultra-fine focus control. The 2.0" diagonal accepts 2.0" eyepieces, and its optical path is reported to provide up to 99% light transmission.

The Series 5000 OTA can be attached to standard photo-style tripods with its included mounting bracket that offers 1/4"-20 mounting bolts. This mounting bracket can also be secured to the existing dovetail on Meade's LXD75 tripod without modification.

Product Series

For crisp wide field observing and imaging, nothing can beat a true triple-element apochromatic refractor (APO). This is especially true in astrophotography, where APOs have produced some of the most beautiful images of the heavens ever taken from earth. But not all APOs are created equal. Today's market is filled with semi-APOs (with two lenses instead of three) that don't bring all the colors to focus in the refractor. Thanks to a two-year design process and a triple objective lens made from the highest quality ED (extra-low dispersion) glass, Meade Series 5000 ED APO Triplets are virtually free of chromatic aberration (color fringing). This means they outperform the most expensive semi-APOs at a fraction of the cost. Expert observers will be delighted by the total absence of color fringing and the scope's textbook-perfect pinpoint star images. Even beginners will notice the breathtaking high contrast and resolution of a Series 5000 APO. One astronomer commented that the Series 5000 APO "kicked butt on my semi-APO that cost twice as much." The scope is available as a standalone OTA, or as a package with our new Series 5000 2" enhanced diagonal and an aluminum carrying case.

* FAST FOCAL RATIO: At f/6 (80mm) the focal ratio of these scopes is tailor-made for fast wide field astrophotography. * PREMIUM ED GLASS: Meade uses the finest Japanese FCD1 ED (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 Series 5000 APOs. * FULLY MULTICOATED LENSES: Meade broadband 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. * FULLY EXTENDABLE DEW SHIELD/SUN SHADE: An essential accessory built-in to the design for your convenience. Optical Design 3-element Apochromatic Refractor Optical Diameter 80mm (3.1") Telescope Dimensions 15" x 4.9" x 4.9" Focal Length; f/ratio 480mm; f/6 Dew Shield Built-in Extendable Optics Fully Multi-Coated Focuser Machined Aluminum Crayford Weight (OTA only) 6.2 lbs.
