Lunar phase

Lunar phase page 8 - terminator ~E30--E00

Lunar phase pages show samples of almost all archived nights. These pages, however, do NOT show ALL images. If seeing has been poor, only a few samples are included; under good seeing conditions a larger collection may be shown. For each night seeing is printed on the first image.
Most phases are opened with two similair looking images. The first one is originally a single image where lunar diameter is somewhere between 1760-1930 pixels. The second one (it has letters "ISO" in the given name) has diameter somewhere around 5000 pixels and they have been composed of separate higher magnification images.
Phase images are followed by crater views from that particular night. These images are also the same which have been used to compose the larger phase images above and so this is also their resolution. Crater images have their size typically close to 1700 x 2250 pixels.
Finally, on some occasions averaged crater views are posted. This means that 2-4 similair images have been averaged to diminish pixel artifacts; in general such images are a bit softer (seeing is never perfect and causes distortions) but on the other hand they are also smoother pixelwise.
