DayStar 0.5x - 0.33x Imaging Focal Reducer for Daystar Quark
- 349,00 €
DayStar's Imaging Focal Reducer can give you more field of view in your images. 2" to T mount, with included T extension tube for even more reduction.
With a T-mount camera connected directly to the reducer, the focal length is cut in half - 0.5X. Add the 20mm extension tube for 0.33X. Even better is to combine the T-thread Interference Eliminator (sold separately) with the reducer for an interference-free 0.38X effect.
Please note that the obtainable field of view is usually limited by the etalon clear aperture; Quantum filters will result in a larger usable field than Quark or Ion.
