 This pair of images were taken a day before
            full moon, and on the wider field prime focus image at left,
            spans from the brilliant white rayed crater Kepler on the lower
            left, to the small basin on the upper right terminator which
            is the crater Grimaldi. There are many ghost craters in this
            part of Oceanus Procellarum appearing as white incomplete rings
            buried in the lava.

            
The image on the
            right is with the 1.8x barlow, as much as seeing would permit.
            Riccioli just to the right of Grimaldi is just starting to catch
            the light on its rims.
