Description

Sinus Iridum – The Bay of Rainbows. In this image clearly showing its classical Jewelled Handle, comprising an illusionary setting for 5 gemstones, only visible for a few short hours each month when the terminator passes over the basin. The low sunlight illuminates the Jura mountains with a Clair-Obscure effect at 2 days after first quarter setting the valleys in deep shadow while highlighting the prominent peaks creating the visual effect of a Jewelled Handle. It is a highly prominent and imposing feature which stands out against a background of darkness which is difficult to image correctly while retaining the low Dorsa wrinkled wave like features within the bay that also come to prominence at this time. Another hugely important and stand out feature of this image is the “Moon Maiden” first brought to prominence by the Italian astronomer Giovanni Cassini in a drawing published in 1679. “She” can be seen in the structure of the Promontorium Heraclides overlooking the peaceful bay. (to best view the Maiden, rotate the image 90 degrees counterclockwise). Other standout features are the Promontorium Laplace, the small crater Laplace A at the entrance to the bay and the crater Bianchini in deep shadow on the crest line of the Montes Jura. To the right of the image are the craters Helicon and Le Verrier.
