Vixen SD115S Refractor Telescope

Features High-quality SD refractor with 115 mm aperture Bright, pure-color and extremely sharp image Also suitable for full-frame cameras Portable and lightweight, despite large aperture Very high contrast thanks to SD glass Ideal for observing the moon and planets Description A new apochromatic refractor with high-performance Super ED glass (=SD). The FPL53 glass reproduces an extremely clear and sharp image by eliminating residual chromatic aberration. Another advantage of these SD refractors is their short length and lightweight design. The SD glass is designed to focus all beams of violet, red, blue, yellow and green light exactly onto the same level. The special lens material reduces chromatic aberration across all colors. Together with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors provide illumination with a 44 mm image circle for full-frame SLR cameras. The ED81SII, ED103S and ED115S refractors were originally designed for visual observers or photographers with an APS-C camera. However, the new SD series features new inner panels which are optimized for full-frame cameras. The large focuser allows you to attach heavy cameras without the telescope tilting. The telescope also comes with a folding mirror for making observations in unfavorable conditions, as well as a T2 thread for connecting a DSLR camera.
