The Vixen ED103S is an apochromatic refractor which has fantastic contrast and a competent 4" aperture sufficient for viewing most of the planets and many stars. With its ED glass elements chromatic aberration has been reduced to nearly undetectable levels permitting a much more practical use of the higher magnifications than when using other achromatic refractors of seemingly identical specifications.Vixen's ED Glass has brought refractors back to the forefront of premium telescope choices to compete with the 8" and larger ubiquitous Schmidt-Cassegrains that while bringing in enormous quantities of light simply cannot compare to the contrast of the apochromatic refractor.The included flip-mirror adapter allows either 90 degree or straight-through observing. With an eyepiece on each end of the flip-mirror you can quickly switch between the two as the declination of your object of interest changes its location in the sky.The new lenses focus the full visible spectrum of visible light to a critical point much more accurately than past ED product.
