Svbony 0.5X Focal Reducer
Buy on Amazon
The Svbony 0.5X Focal Reducer is a compact optical accessory designed to halve the focal length of a telescope, effectively widening the field of view and reducing magnification for broader sky coverage. It threads directly into standard 1.25-inch eyepieces via an M28x0.6 thread, making it a relatively easy drop-in addition to most setups. Overall it offers a budget-friendly way to achieve wider views, though users should be aware that some edge-of-field softness is common at this price point.
