July 20, 2012 Venus Jupiter Conjunction Sky Map Experiment

Constellation Auriga with bright star Capella
Friday morning was clear enough to capture Venus Jupiter conjunction and the most stars ever photographed in the early morning dawn sky. This experiment shows that a simple hand held camera shooting a very clear sky at high ISO ratings can create a "downtown" star map from a heavily light polluted high density populated city. This 1 second exposed (2 EV) image was taken at 4:20:06 am with settings of f/2, a 28mm lens, and ISO 1,600. No UFOs were seen during the sequence of observations. Enough stars are seen to clearly define the constellations. This view is screen captured from the original 1064 x 1600 pixel image. The star map is rotated to match the actual view of the constellation Auriga and the brightest star Capella, in the photo to the left of the Taipei 101 skyscraper. The photo shows the Pleiades star cluster, Venus, Jupiter, Aldebaran in the Hyades star cluster, and the constellation Auriga with the bright star Capella. A PowerShot Canon S95 CCD camera was used to obtain the sequential images in this study. The camera eye is recording numerous stars not seen to the naked eye view. To conduct a program of creating the aforementioned sky maps, a simple tripod is recommended. It may also be possible to go deeper on the exposure and this deserves continued experimentation. The Lab 50 is obstructed by a brick structure on the South, so for an all sky mapping project another lab is recommended, like Area 51 atop the skyscraper.
