Theophilus - Lunar Observation

Date: 07 January 2007
Time: Centered around 12:00 U.T.
Telescope: 80mm f/5 refractor
Magnification: 65x
Seeing: Fair-Good
NELM: 5.1 or better
Temperature: +20 F (-7 C)


The above sketch shows Theophilus (the large formation) and the nearby crater, Madler. West is toward the upper right. South is toward the lower right in this mirror-reversed view. Some of the surrounding details were very hastily rendered, resulting in a more inaccurate sketch. I really need to start using my larger refractor, on it's sturdier (tracking) mount while I sketch comfortably seated. The at-the-telescope sketch that the above was based on was made while standing. The telescope was on a homemade alt-az mount that was set up on a porch -- not the best of situations! Nevertheless, I wanted to continue with a bit of lunar observing and sketching.
