The 61EDPH Ⅲ upgraded the handle of the 61EDPHⅡ to a multifunctional handle, which can be connected to the universal vixen-style finder base. 61EDPH Ⅲ has a focal length of 360mm, a focal ratio of 5.9, and supports the 44mm full-frame image circle. It not only can be applied to visual observation, but also can provide higher-quality astrophotography. Compared to the 61EDPHⅡ, it upgraded to two pieces of low dispersion ED glass for more excellent imaging performance. The new 61EDPH Ⅲ still has high-quality optical standards like before and adopts a triplet air-spaced APO design. It is a great choice that can't be missed by astrophotographers.
61EDPH Ⅲ has more diverse functions and greater performance. The 61EDPH series has long been popular with astrophotography amateurs, in order to have a better user experience for users, Sharpstar has optimized the 61EDPHI Ⅱ and launched a new version - 61EDPH Ⅲ.
