也接受ES152APO 127APO的预定，碳纤维版的晶华200MM的折返也即将到货几套，ES的100度25mm,5.5mm也到几个。欢迎提早预定，数量有限
ES127资料
This Explore Scientific ES127 CF refractor has:
• 127mm f/7.5 fully multicoated triplet optics using a Hoya FPL51-equivalent ED element
• lightweight low thermal expansion carbon-fiber body
• dual-speed 2" Crayford focuser with 10:1 ratio fine focusing
• 2" dielectric star diagonal with 2" and 1.25" brass compression ring eyepiece holders
• 8 x 50mm illuminated erect-image/right-reading finderscope
• dual split mounting rings with dovetail for installing on a Vixen-style altazimuth or German equatorial mount
• flight-ready travel case
• lifetime transferrable limited warranty With a 5" (127mm) aperture, this Explore Scientific ES127 CF ED triplet refractor gathers 55% more light (with nearly 25% higher resolution) than the more common size 102mm (4") doublet and triplet refractors that often cost nearly as much as the ES127 CF. The Explore Scientific ES127 CF uses a premium Hoya ED glass element and state-of-the-art optical multicoatings in its apochromatic air-spaced ED triplet optics. The result is images that are essentially free of the annoying halo of unfocused violet light (chromatic aberration) that mars the view of bright stars and solar system objects in lesser scopes, despite the scope’s relatively large aperture, and even at very high magnifications. The 127mm Explore Scientific triplet optics are even more appealing when you consider that this Explore Scientific apo is loaded with features other manufacturers charge extra for (or don’t even have available) – such as an illuminated 8 x 50mm finderscope with erect right-reading images, a 2" dielectric star diagonal with 1.25" and 2" compression ring accessory holders, and a flight-ready carrying case. The body and dew shield of the 127mm Explore Scientific are made of high strength, low weight, low thermal expansion carbon fiber. This keeps the scope light in weight and sharply focused as the ambient temperature changes during critical long-exposure CCD imaging. The Explore Scientific ES127 CF is a natural on an equatorial mount as the heart of your primary observing system. In addition, it’s an excellent astrograph for serious wide field imaging, as well as crisp solar system imaging. Considering its surprisingly reasonable price for a 5" apochromatic triplet, adding in the extra features you get at no extra cost, and in view of the great optical performance that comes as standard equipment, the 5" Explore Scientific ES127 CF is a terrific buy!
