Vixen ED80S 80mm f/7.5 ED Apochromat RefractorThe ED 80S was initially listed as an entry level APO, but now with so many astronomers giving such glowing reviews, it appears that Vixen will need to reclassify this product! The ED80S refractor features high-grade glass and quality components. Coupled with a medium f/7.5 focal ratio, the ED "S" series provides a sharp, color-free image of high contrast. At only 22.4", this is Vixen's ultimate grab-n-go APO travel scope. The ED80Sf comes complete with a 9x50 finder-scope - Finder bracket - 2" eyepiece adapter - 1 ¼ Flip mirror - Tube Rings - Dove-tail plate - Aluminum Telescope Case.
