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! If you mean entry-level to high-grade glass and quality components, then, yes, that is an apt description. Coupled with a medium f/7.5 focal ratio, the ED 80Sf delivers a sharp, color-free image of high contrast. At only 22.4", this is our ultimate grab-n-go APO travel scope.
The ED80Sf comes complete with Aluminum Case, Flip Mirror, finder Scope and Rings. The ED80Sf works beautifully with the award winning Porta II Mount. Vixen's Porta II Tall Mount is a solid alt-azimuth mount with a 20lb payload capacity and features high end slow motion knobs to track subject precisely. The extra height on this mount makes it ideal for refractors or taller individuals. A solid observing platform with slow motion controls for smooth tracking.
