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.
