As seen to me just now, the Planet Venus in a waning gibous phase with an illumination of 33%, through a four inch Achromatic Refractor Telescope at 50x.
In a telescope, Venus has enlarged to 33 arcseconds in diameter while waning in phase to become a thick crescent 1/3 sunlit. Venus will continue to enlarge and wane, finally becoming a dramatically thin crescent low in twilight in late May as it approaches conjunction with the Sun.(Sky and Telescope)
