Sky Haze Experiment with Venus Jupiter Conjunction

SKY HAZE EXPERIMENT WITH VENUS JUPITER CONJUNCTION

SATURDAY JULY 21ST 2012

4:39:40 am

This test exposure is maximum processed to show clouds and haze (at top of photo) that was not visible to the naked eye. It's obvious that on nights of this typical haze, which apparently is often, the limiting magnitude takes a reduction hit. Planets shown are Jupiter and Venus next to Aldebaran in the Hyades star cluster in the constellation Taurus the Bull. This is a screen capture from the original 1016 x 1529 (752K) image. Exposed at 1/10th second, the ISO 1,600 image was at f/2 with a 28mm lens without zoom, using a Canon PowerShot S95.

The next color photo shows a normalized enhanced conjunction view with two planets and three brighter stars including Aldebaran in Taurus (at right of Jupiter and Venus) and Capella (far left) in the constellation Auriga, visible in this early morning dawn view. The conjunction view shows less stars around 4:30 am due to the encroaching sky glow. However, earlier clouds prevented completely clear sky imaging. Refer to the previous conjunction images for the identification of stars.




 
In the next view, a kind of "Where's Waldo" of stars, shown at larger image scale, a maximum number of eight stars are visible. Two above 101, four at left, and three at top.
