Vixen ED115S Refractor with Accessories
The ED115S is a splendid example of an imaging telescope, ideal for those looking to get a handle on astro-photography and put their foot in the door. This is a great choice for someone transitioning between visual and imaging astronomy, and is suited to both applications. And regardless of how you choose to use the ED115S, you'll find it to excel in certain ways no matter what. For one it boasts a design and optical glass quality that nigh utterly eliminates chromatic aberration! The optics are simply excellent, showcasing excellent sharpness, contrast, and correction all throughout the field of view. The new 'SD' type lenses from Vixen manage to produce brighter images from the shorter f/7.7 focal ratio to capture crisp, pinpoint star images for your enjoyment. The astro-photographer will be especially pleased with the high contrast images through this telescope and the full objective diameter of 4". The SD lenses focus all visible rays of light at nearly the very same position. This ensures that the chromatic aberration is highly corrected over a wide spectrum of light. Of special note is the g-ray light, which affects image contrast, is well suppressed.
