Subject: [Leica] Don't photograph the eclipse correction

Apparently there was a glitch in my eclipse message. I wrote "Remember that 
the image on your camera?s sensor is only about 9 percent of the focal 
length of the lens." Actually I meant to say that the image on the sensor or 
film is the focal length of?the lens divided by 115. Thus for a 1000 mm lens 
the image of the eclipse is about 8.7 mm. OK if you are using a full frame 
sensor or film but a far cry from the size of?the image recorded by a real 
telescope.
