Incredible detail stands out along the terminator of the eight-day Moon.
This was the Moon on the evening of April 26, with the waxing Moon eight days past New and one day past First Quarter Moon. It’s a great phase to explore the surface of the Moon.
In the north the arcs of the Alps and Apennine mountain ranges encircle Mare Imbrium.
In the south, craters pepper the Highlands in stark relief. Tonight, the Straight Wall was just beginning to catch the light of the rising Sun, creating a very sharp, straight shadow.
The regions along the terminator – the boundary between light and dark – at left are seeing the first sunlight in two weeks. To the right, on the more brightly lit portion of the near side of the Moon, the dark mare areas stand out in various shades of grey. Systems of rays splash out from bright, geologically fresh crater impacts.
On the technical side, this is a mosaic of two overlapping images, one for the northern and one for the southern hemisphere, taken through a Celestron C9.25 telescope at a focal length of 2300mm. I stitched them with Adobe Camera Raw’s new (as of last week’s update) ability to stitch images into a Raw-format panorama file.
