  • Barn Door Tracker with Variable Speed Motor - My Bard Door Tracker I decided to build a “Barn Door Tracker” so that i could have a portable mount for taking astrophotos with a wide angle lens. Something that i could setup quickly and was compact and light. But the main purpose was a “make fun” project that involved some mechanical design and an opportunity […]
  • Vallis Alpes Comparison – 2013-04-21 - I recently came across an image of Vallis Alpes on the moon (Alpine Valley) created by the Lunar Orbiter 4 space craft in 1967. It struck me as amusing that my own image taken in April of 2013 compares favourably with the Obiter’s image. The Orbiter’s altitude varied from 2,100km to 6,000km so I nominally choose […]

And it’s a relatively modern story considering the ancient folklore associated with the constellations and the heavens in general. In 1920 there was a raging disagreement among astronomers and scientist in general about the size of  universe. The generally accepted view […]
  • Vega and the Constellation Lyra – 2015-10-30 - The bright star Vega at magnitude 0.03 is the 5th brightest star in the sky and the third brightest star visible from the 45th parallel (Ottawa). Sirius at magnitude -1.46 is the brightest star in the sky and Arcturus magnitude -0.05 is the second brightest in the north. Although the yellow-orange star Arcturus is only […]
  • Lunar Eclipse – 2015-09-27 - The weather reports of the preceding days and even the day of the eclipse predicted clear skies. So i planned a photography project to create a time lapse sequence covering the entire event from penumbra advance, through total eclipse and then the receding shadow. As it turns out, the clouds moved in about the time […]
