• The DayStar Imaging 2-inch Focal Reducer connects directly to your reducer to cut the focal length in half (0.5x), or add the extension tube for a 0.33x reduction.

  Please note that the etalon clear aperture usually limits the obtainable field of view; Quantum filters will result in a larger usable field than Quark or Ion.

  Allows full disk imaging with SR127 and two-third-inch monochrome CCDs such as ICX625, ICX655, IMX250, IMX264.
