Like a Tart

Lacus Excellentiae

 “She appears like a tart that my cooke made me last weeke, here a vaine of bright
stuffe, and there of darke, and so confusedlie all over. I must confess I can see
none of this without my cylinder”.
  
  These were the honest words of William Lower an amateur astronomer written upon
observing the Moon with his new “perspective cylinder” in 1608.
  In the history of Man Kind this is but a heart beat in time but how the telescope
has evolved from that primitive Galilean spy glass that only the privileged few
could ever hope to own! Now even the most modest instrument delivers views of the
heavens and Moon in particular that our astronomical forefathers could only have
dreamt of!
  
  One thing that hasn’t changed for me and countless others is the “confusedlie” of
the Moon. It is an awe-inspiring yet bewildering sight to all but the most
experienced lunar observer. I myself am very much a Lunar apprentice and each time
I fly over the terminator with my telescope and settle upon “she who takes my
heart” I am learning my way around not only the shadows, bright ridges and crater
rims but through my post sketch research feature names, dimensions and geological
composition.
  
  On the late evening my visual voyage of 250,000 miles at the eyepieces of my
binoviewer was just such an adventure.
  I deliberately selected a relatively demure region, shunning the bright and large
craters in a deliberate attempt to stray from the well trodden path.
  
  It turns out that my target area turned out to be Lacus Exellentiae. I was
initially drawn to a crater with a brightly lit rim just to the left of centre in
my drawing that my subsequent atlas searches found as being nameless apart from
being marked as (b) in a few of the atlases I own . The crater on the right close
to the terminator however turned out to be Clausius with a diameter of 24km and
was situated close the controlled crash site of the European Smart -1 Lunar
orbiter on September 3rd 2006.
  
  A happy hour spent and no longer so Confusedlie!

  1. Dale,

    A most excellent sketch and narrative. Those bright crater rims are quite eye catching.

  2. Dear Frank,

    You always say such nice things, thank you. I have just learned how to increase the resolution of my scans this might hopefully mean that my future submissions may look a little more attractive.

    Have a great weekend all, Dale
