Clear skies / "Bright skies aren't empty skies" (James Mallaney)
My best solar system sketches / My deep sky sketches
Quote:... The seeing had improved considerably by then and the moon looked like a cream colored three dimensional orb. Once it cleared the limb, it reverted to appearing like a 2-D disk...
Quote: Always nice to have one's observations confirmed--especially by another visual observer.
Quote:Thanks, everyone! :...if I understand you correctly, the spherical appearance of the moon is caused by being backlit by Jupiter as well as front lit by the Sun?
Quote:As far as this phenomenon being a function of aperture, I have observed it many times with my 20cm SCT, too.
