I do not design a machine which will give the ignorant in astronomy a just view of the solar system, but would rather astonish the skilful and curious observer by a most accurate correspondence between the situations and motions of our little representatives of our heavenly bodies and the situat...
Adding or subtracting days, as the Julian or Gregorian calendars do, to adjust the seasons will not work, since this will ruin correspondence to the Moon. The best convenient rule for the Sun is thus still the Babylonian 19 year cycle. The continued fraction for the number of synodic months...
Cloudy skies are forecasted for Monday across most of the state andNational Eclipsesays even "a few stray clouds" can ruin the big moment. Chances are, we'll still observe the event, but if heavy cloud cover persists, it won't be nearly as remarkable. Keep an eye on the forecast and ...

Don't let poor focus ruin your images. Allow yourself enough time to focus carefully to get sharp images. If possible, prefocus your camera (without the solar filter) the night before the eclipse using a bright star. Otherwise, focus carefully (through the solar filter) on the sun's limb...
we have no garden (and even IF we put our solar lights in/on cedar blocks, I’m pretty sure the lawn “care” guys would ruin those as well as they’ve ruined the 1st 3 sets I had around the cement patio/pergola area) but absolutely LOVED reading the post .. hilarious and ...
