Vallis Alpes

May 23, 2018. 500 frames with a 1024x768 region of interest, ZWO ASI183MC Pro, stacked and processed in Registax 6. When I first looked at the moon through a telescope, this amazingly straight line riveted my eye. A "grabgen", fault about 200k long, assumed to be an after effect of the Imbrium basin impact.
