Vixen - ED103S 103mm ED Apochromatic Refractor Telescope Package with GPD2 Mount

The newly designed high definition ED lens on the ED103S gives excellent optical performance with
a short optical tube for easy handling. The new ED lenses feature brighter images from the
shorter f/7.7 focal ratio and capture crisp, pinpoint star images for your eye’s enjoyment. The
new ED103S lenses are made with environment-friendly technologies, free of hazardous lead that
helps to support a cleaner global environment.

The optical tube comes equipped with a metal carry handle for easy one-hand carrying. The new
lenses focus the full visible spectrum of visible light to a critical point much more accurately
than past ED product. The ED103S lenses are almost free of chromatic aberration in all colors and
are critically sharp edge to edge. The astro-photographer will be especially pleased with the high
contrast images through this telescope.
