About this product
This useful 0.5x focal reducer can be used with a wide range of modern CCD cameras and eyepieces.
The doublet optical system features fully multicoated glass elements for enhanced contrast.
The 1.25" filter-thread screws into regular 1.25" eyepieces, cameras and other photographic accessories to achieve a 40% increase in field of view.
Effectively reduces the focal telescope's length by 50%.
NOTE 1: The exact focal reduction varies slightly depending on the position of the Focal Reducer relative to the eyepiece' optics or, when imaging, to the camera's imaging sensor.
NOTE 2: Not recommended for short focal ratio systems.
