That Funny Figure 8 Shape

We have come a long way since the days of photography with film (and YES I still use film when it is warranted)… digital cameras have made this particular project a lot less worrisome and a lot easier, though it is still not without its challenges. The goal: take 50 plus images of the southern sky at clock noon throughout the year to catch the solar path, the analemma.  We were blessed with a clear winter solstice day this past December, so I said “why not give it s try… again…?” So here I am, now into the last week of January and with a slew of good images… not great… but ok. Key Points:

  • It is more often cloudy at noon than not. 
  • I am usually busy at noon and no place near the camera’s location.
  • A wide field lens on the camera, a solid tripod and registration marks in the viewfinder make this easy. There is no need to permanently mount a camera these days.
  • Photoshop makes combining images and getting the last bit of perfect alignment easy. 

Here is a shot of two days: solstice to now (29 Jan 2017).  We have two suns!  AND it has moved quite a bit since the solstice.  Days are getting longer. Yay!
