TECNOSKY EDT 80/480MM V2

This FPL-51 ED triplet refractor manages to provide excellent performance in both photographic and visual fields but at a low price.

Despite the use of a less valuable glass than the FPL-53, the triplet optical scheme allows for very good color correction, better than the classic ED doublets.

The bright F6 focal ratio is ideal for deep-sky photography; in combination with the 0,8X reducer / flattener it becomes a perfect F4,8 astrograph at an affordable price!

With a weight of only 3.5kg and a length of 355mm it becomes the ideal companion for the traveling amateur in search of dark skies.

The V2 version has a new intubation with the robust 2.5 "RP focuser.
