Vixen - SD103S apochromat refractor and SX2 mountadd this item to shopping cartThis product is highly recommended
Code: 25102
Vixen 103mm ED apochromat refractor with SX2 equatorial mount and StarBook 1 controller for visual and auto-guided astro-photography


A classic Japanese design telescope and mount, the ED103S optical tube features a 2 group 3-element ED optical design with special Ohara FPL53 ED glasses which dramatically reduces secondary spectrum and produces incredibly good views of high contrast for both visual work and astrophotography. It is the ultimate fast refractor for serious observing and photography with plenty of aperture and the thermal benefits of sealed optics. This is a new generation of highly corrected Japanese ED optics not like those found in budget models.
Seen here with optional carry handle, finderscope and flip mirror.
