Above-average contrast

The Reducer HD features the optical coating that was developed by Vixen for our high-end VSD100F3.8 astrograph. The AS coating provides light transmission of up to 99.9% per lens surface. The special matte surface in the interior also minimizes ghosting, light loss and lens flares.

Reducer HD in combination with SD telescopes
The Reducer HD can be used on telescopes from the SD series (SD81S, SD103S and SD113S) with the SD Flattener HD Kit (item #37246) . The Reducer HD reduces the focal length by a factor of 0.79x (f/7.7 to f/6.1) and delivers a razor sharp image over the entire 44 mm image sensor surface on DSLR cameras.

Reducer HD in combination with AX103S and VC200L telescopes

• Up to 99.9% light transmission per lens surface
• Reduces the focal length by a factor of 0.79x
• Also suitable for full-frame DSLR cameras
• For the ED/SD 81S, 103S, 115S
• AS coating with light transmission of up to 99.9%
• The focal length of the VC200L is reduced from 1800 mm to 1386 mm. Speed increases to f/6.93. The image circle has 36 mm diameter.
• The focal length of the AX103S is reduced from 825 mm to 635 mm. Speed increases to f/6.16. The image circle has 44 mm diameter.
• With the AS coating, a transmission of up to 99.9% per lens surface is achieved, with total absence of ghost images and reflections.
• The reducer has the Vixen M60 thread (male/female) at both sides and additionally provides a 52x0,75 filter thread at the telescope side.
