Vixen’s new SD apochromatic refractor features high-performance Super ED Glass (=SD) made of leading-edge glass to deliver extremely clear and sharp images by eliminating color aberration. The SD glass is designed to gather all g-ray (purple), C-ray (red), F-ray (blue), d-ray (yellow), and e- ray (green) to about a “0” value, which makes this excellent lens material that reduces chromatic aberration over all colors. 

The light baffle positions in the drawtube are arranged to take advantage of the entire field of view of a DSLR camera with a full frame image sensor. When used in combination with the new optional SD Reducer HD Kit or SD Flattener HD Kit , you will have a 44mm image circle with full-format (D)SLR cameras.

The Reducer DH, sold separately, includes the SD Flattener DH and is essential for wide field astrophotography with the SD Scopes. Eyepieces sold separately.
