It's actually four planets. Venus, Mars, Jupiter and Saturn. All images captured 2012-02-25. Filing this as Illustration / Art because of the amount of editing to put them together. But they are real captures not otherwise edited.
Telescope was a Celestron 8" Dobsonian (essentially a Newtonin Reflector on a swivel Alt-Azimuth mount).
1) Venus taken with my Canon EOS Rebel XTi using "eyepiece projection" - I held the camera to the eyepiece, probably a 25 mm Plossel, of the telescope and snapped the shot. The image is cropped to 640x480 to match the format of the QuickCam Pro images. Venus, because it is inside the orbit of the Earth shows phases similar to the Moon.
2) Mars, captured at prime focus with a Logitech QuickCam Pro 4000 (640x480 sensor). The little red dot down and to the left is likely a glitch in the webcam. It wasn't there in the telescope.
3) Jupiter, again with the Logitech QuickCam Pro 4000. This time the little white dot barely visible to the left IS there. That's the Jupiter moon Io, just emerged from behind the planet.
4) Saturn, one more time with the Logitech QuickCam Pro 4000. I think It might be slightly over exposed, but this image was captured at 320x240, I matted the image to fit the 640x480 format of the others. At least I caught the rings.
