Reviewed in the United States on February 9, 2021
The Quilu 0.5x focal reducer was a big disappointment. The alignment of the optical elements within the reducer is improper resulting in conic (hyperbolic) distortions for point sources (stars, planbets) that are so severe that the item cannot be used for its intended purpose.
