The ED 80SF was initially listed as an entry level APO, but now with so many astronomers giving us such glowing reviews, it appears that we will need to reclassify this product! The ED80Sf 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 our ultimate grab-n-go APO travel scope.
