Three day old moon, 9.4% illuminated. Langrenus to the right, Dorsa Andrusov the subtle feature in the centre of the field of view resembling an X chromosome (if you know what one lookes like!), and Mare Spumans above this, the smooth, walled off mare which seldom gets a mention.

The ProPlanet 807nm filter cuts down the incoming light significantly so exposure times and frames rates are slow, and I ended up with very little data to stack. Best 5% of 2000 frames stacked in AutoStakkert and sharpened in WaveSharp. Levels curves and other illumination done in FastStone Image Viewer.
