Special June Pricing. Reg. $1199 Now $999.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.
