Chromatic Aberration
http://upload.pbase.com/image/48689707.jpg
Shows the result of photographing Venus with an "ultrazoom" digital camera. Venus was about ten degrees above the horizon. Could the effect show be caused by atmospheric refraction, or is it more likely to be a deficiency in the camera lens? -- Gerry http://www.pbase.com/gfoley9999/ http://www.wilowud.net/ http://home.columbus.rr.com/gfoley http://www.fortunecity.com/victorian...ypt/egypt.html

Exposures with a tripod tonight convince me that whatever was goimg on, it wasn't atmospheric refraction.
