Transit of Mercury, November 8 2006
Up until one hour before first
contact, the sky was completely overcast with light showers, so I had to
setup my equipment with an umbrella and plastic covers over the optics
and electronics. Half an hour later, the sky was clear; although,
there were light winds with a few moderate gusts.
I used a Meade LX200GPS 10" telescope equipped with a Neutral Density-5 Solar Filter. For the videos I used a Watec 902-H CCD camera connected to a KIWI Video Time Inserter. Closeup videos were taken with no Focal Reducer. At various points throughout the transit, I stopped the video recording to connect a Nikon 35mm SLR camera to the telescope.
The composite image above was taken with an F6.3 Focal Reducer in front of the 35mm camera. The image consists of 6 images combined using Adobe Photoshop. The six tiny dots "moving" left to right is the planet Mercury. During the almost 5 hour transit, the large sunspot 0923 also moved a bit. Click on the image to view a larger version.
At times during video recording, I added an F3.3 Focal Reducer for a wider field of view. The black and white image below was taken from the video just after second contact.
I also used a 26mm eyepiece to get some close up images with the 35mm camera. The color image below shows sunspot 0923 to the left and Mercury to the right.
Around the midpoint of the transit I took another close up with the 35mm camera, and then later I zoomed in on the planet with the video CCD.
Except for a few gusts of wind, the weather held through out, so I am pleased with the results. Mercury was right on time, and exactly where SkyMapPro said it would be. By the end of the transit, the Sun was only 8 degrees above the horizon, and conveniently set between two trees in my back yard.
For creating the following time-lapse video files, I used an Adaptec VideOh Analog to Digital converter, VirtualDub and Windows Movie Maker.
