Hi all,
We had a great spell of clear nights last week that allowed
me to do three sketches of the Moon over three consecutive nights. The first was a revisit of Copernicus that I
had sketched the month before but on a more advanced phase.
On this particular night, the phase was two days after
Copernicus’ appearance on the terminator.
This made for a shallower angle of incidence of sunlight so many more of
the smaller secondary craters to be visible.
Conditions on the night were not brilliant, and magnification at 250X still
saw a lot of atmospheric thermal current distortion to the image, limiting how
small the details I could see. With a
bit of perservierence a lot of these secondary craters could be made out. You will find information on the formation of
these ‘secondary impacts’ in my earlier write up on Copernicus below.
Being sooner after sunrise over Copernicus, the shadow
structure made for a more dramatic lunarscape.
Longer shadows, greater contrast, and a visual feast. The surrounding craters that accompany Copernicus
also adding to the drama with there illumination.
