Description Technical Specs
 
Designed for Vixen's R200SS Newtonian Reflector telescope, turns the R200Ss into an f/5.6 astrograph. The extender PH kit is designed to extend the focal length to 1.4x. The R200SS Newtonian Reflector (800mm, f/4) will be extended to 1,120mm , f/5.6. This component uses an optical system of 4 elements in 3 groups and coma aberration eliminated enabling you to capture sharp images to the edge of the imaging field, while complying with a full frame camera 44mm image circle. Using a 31.7mm eyepiece in combination with an eyepiece adapter allows for visual observation.

The PH Kit features the same AS coated anti reflective glass that is found in our VSD100f3.8 Astrograph to take advantage of the 99.9% superb transmission of light. Loss of light, ghost and flare images are eliminated substantially with the PH Kit due to the matte finish inside. The use of a 50.8mm eyepiece adapter with the extender PH Kit enables you to use it like a high performance barlow lens for visual observation while coma aberration over the entire viewing field is is eliminated
