SD115S Apochromatic Refractor Tube Vixen
A new apochromatic refractor with high performance Super ED (=SD) glass.
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 violet, red, blue, blue, yellow and green light beams at exactly the same level.
The special lens material reduces chromatic aberration in all colors.

Together with the new optional SD Reducer HD or SD Flattener HD kit, these refractors provide 44 mm image circle illumination 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 incorporates new interior panels optimized for full-frame cameras.
The large focuser allows heavy cameras to be attached without tilting the telescope.
The telescope also includes a folding mirror for observations in unfavorable conditions,
as well as a T2 thread for attaching a DSLR camera.
