Description

The Vixen ED refractor range has been redesigned in order to allow the use of full frame DSLR camera sensors and yet are still compact and portable. The range is now designated SD (standing for Super extra low Dispersion glass) and includes the same 81mm, 103mm and 115mm variants.

Thanks to an improved baffle system, the incoming light near the edge of field of view has been increased when compared to the previous generation models.

The SD range now has its own dedicated field flattener and focal reducer. These help to deliver pin sharp star images across the field of view of a 35mm full-frame image sensor.

At only 625mm in length the SD81 is the smallest and most portable in Vixen's new SD range. Perfect for observation and imaging on the move.
