Venus Jupiter Aldebaran Conjunction

NOTE: YOU CAN View this ongoing planetary conjunction of Venus and Jupiter with the star Aldebaran all throughout the month of July 2012.
IMPROVING CONJUNCTIVE VIEW STUDY
Tuesday July 10th 2012
Several factors improved images of the ongoing planetary conjunction with Venus, Jupiter and the star Aldebaran in the constellation Hyades. An earlier observation time led to a darker sky and better contrast and fewer clouds compared to the previous observation made the event appear spectacular. In this view, the focus is slightly offset to successfully make larger planetary dots and more accurately represent visual brightness levels. Jupiter is above Venus and the star is very close to Venus at the bottom right. The first photo shows both planets appearing very bright but does not come close to representing the human eye view which was spectacular. The star is barely visible in this view taken on July 10th 2012 at 4:24:36 am with ISO 1,600 at f/2 and 1.8th second exposure. This is a digitally enlarged snippet screen capture of the original 2594 x 3459 pixel 2.3 MB JPEG image. |

STUDY OF THE EFFECT OF CLOUDS & ATMOSPHERE PARTICULATES RELATIVE TO STELLAR EXTINCTION
In the next photo, taken at 4:27:49 am on July 10th, 2012, the star is clearly visible and most clouds have momentarily passed by this section of the sky. Cirrus clouds appear very light and tenuous although are very good at blocking stars - this is because the city of 8 million has many lights that can reflect off not only the bottom of the clouds but the atmospheric particulates. Keep in mind the clouds can absorb starlight, reflect starlight, and block out starlight with a shroud of reflective brightness. This image was captured with a Canon PowerShot S95 at Telephoto f/3.5 and 12.8mm focus. The 1/8th second exposure was combined with ISO 1,600 sensitivity to compensate for the encroaching sunlight. This is a screen shot snippet from the original 2736 x 3648 pixel 2.9 MB image.

ZOOM CAPTURE STUDY
In the Zoom Capture Study, full Zoom is set to include both planets and the star in the same FOV. This was shot at 4:36:16 am on July 10th, 2012. ISO was increased to 3,200 manually, and the 22.5 mm Zoom focus was combined with a 1/4th second exposure at f/4.9. This is a screen capture snippet from the original 2736 x 3648 pixel 3.4 MB JPEG image. The Zoom Capture is more suitable for measuring relative object positions. Due to the fast ISO and relatively fast exposure, this and similar images are made possible by merely holding the camera by hand.
OBSERVATIONS OBSERVATORY
These observations were made at Observatory Lab 50. The Lab is very convenient at it locates off an adjacent wing to Static Lab 49 where images are processed. For higher resolution on similar Zoom studies, shoot in RAW mode rather than JPEG mode to increase resolution and reduce artifacts.

| Two more stars at left seen in between clouds |
At left in the image, two more stars are visible through clearing in the clouds. This was taken on July 10th at 4:27:21 am local time at ISO 1,600 with a 1/8th second exposure (no telephoto) and f/2 lens, using a Canon PowerShot S95 in 2662 x 3550 pixel 4.5 MB file size JPEG mode. The image is cropped and processed in this screen shot snippet.
GRAIN REMOVAL STUDY
Photographic grain at high ISO is removed with Apple iPhoto function. This effect further delineates the cloud to sky differential showing which areas of clearing will have the opacity to show better stellar and planetary viewing.
CONJUNCTIVE COVERAGE
This Conjunction is currently observed a total of four times. It was imaged on July 3rd, July 8th, July 9th and July 10th. Other days were overcast, cloudy or raining and observations were not possible.
