A pair of binoculars will help. For our images, one practical problem is avoiding saturating the camera with too much light. Since the sky is blue and Venus is not, red filters have the additional advantage of emphasizing Venus relative to the sky. For each image dark subtraction and flat fielding corrections were made, and unsharp masking was applied. Finally, adjustment of the brightness and contrast allows us to subtract the uniform skylight and show only Venus in the final images.
North is up and East is to the left.
Each image 139 by 123 arcseconds. The linear diameter of Venus is 12,100 km.
