The Moon and Sun two weeks before the 2017 solar eclipse

Two weeks before the moon will eclipse the sun, the moon was partially eclipsed by the Earth’s shadow

Lunar Terminator 2015-02-25

The moon is always a very regarding target. Even though the slow frame rate of the QHY5 (3FPS!) and the missing IR-Cut Filter do degrade the quality of the final image, some nice detail is visible in this mosaic of three individual avi files. 100 frames out of 400 were used for every frame.


The trio of Theophilus, Cyrillus und Catharina craters at upper left and the Ariadaeus Rille at lower right are prominent features visible in this image. On the floor of the Mare tranquillitatis at lower left some subtle mare ridges are vsible.
