Available again soon - Now with dual speed focuser this superb 80mm triplet ED apochromat refractor with Japanese glass and broadband multi coatings supplied complete with a 2" dielectric diagonal and hard case. For crisp wide-field observing and imaging, few optical designs match the performance of a true triple-element apochromatic refractor which is especially true with astro imaging. Thanks to a two year design process and a triplet air spaced objective lens made from the highest quality ED (extra-low dispersion) glass, Meade Series 5000 ED APO Triplets compete head to head with the worlds premium APOs at a fraction of the cost.BBC Sky at Night magazine group test winner scoring 92%"The 5000 triplet has a three element design that was found to give the best colour correction of all the scopes we tested, indeed we can see no colour fringing at all - stars were really shown at their very best"This outstanding premium Apo package includes the optical tube assembly, lockable hard carry case and the superb Meade 5000 Series 2" Dielectric diagonal with 2" to 1.25" adaptor.Expert observers will be delighted by the virtual absence of colour fringing around objects and the scopes textbook-perfect pinpoint star images. Even beginners will notice the extra high contrast and breathtaking resolution of a Series 5000 ED APO.The three element optical system of the Meade 80mm triplet includes a lens of high quality Japanese Hoya FCD1 ED (Extra Low Dispersion) glass for razor-sharp images that are virtually free of spurious colour across the entire visible spectrum. This special ED glass is noted for achieving 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 triplet apo. All air-to-glass surfaces are fully broadband multicoated for maximum light transmission. Contrast-enhancing light baffles in the optical tube assure truly dark sky backgrounds and high terrestrial contrast.The Meade 80mm triplet has a smooth dual speed 2" Crayford style focuser for minimal image shift, an important consideration for keeping images centered on the small imaging chip of a CCD camera during critical astro imaging. The 2" focuser drawtube uses a soft brass compression ring eyepiece holder that will not scratch the barrel of your star diagonal as an ordinary thumbscrew can. For astro imaging a thumbscrew locks the focuser drawtube in place once you have your camera focused. The precision machined Meade 80mm triplet has a retractable dew shield for dew prevention at night and improved daytime contrast during viewing or imaging. A precision machined aluminium thread on metal dust cap is standard.
