A panorama or mosaic of the 10-day-old gibbous Moon, on March 16, 2019, showing the full disk and extent of incredible detail along the terminator, the dividing line between the day and night sides of the Moon where the Sun is rising as seen from the surface of the Moon. At bottom in the south, the large crater Clavius and above it Tycho in the Southern Highlands are well placed the the dawn sunlight. Tycho is brightening and its rays are beginning to light up and become more obvious splashing across the lower half of the Moon. At lower left on the terminator is the elongated crater Schiller. Above it on the terminator is the crater Gassendi. Above and left of centre is the crater Copernicus. At top the large crater Plato is prominent on the northern shore of Mare Imbrium. On the western shore of Imbrium the curving arc of Sinus Iridum is prominent. I shot this through light haze – in fact there was a halo around the Moon this night. I have boosted the colour saturation and contrast somewhat to bring out the colour difference between the grey Sea of Serenity above center and the bluish Sea of Tranquillity right of centre. Plus differences in the colours of the lava flows in Mare Imbrium show up now. This is a panorama or mosaic of six images, for the southern, middle, and northern portions of the Moon, and east and west, taken through a Celestron C9.25-inch SCT telescope but also with a Canon 1.4x telextender to increase the effective focal lengh even more to 3300mm at f/14. Each segment is a single exposure at ISO 250 of 1/80 second with the Sony a7III. Stitching was with Adobe Camera Raw using Perspective projection.
