Lunar Eclipse On May 15-16
Sayten241 writes "MSNBC reports that on the night of May 15-16 skywatchers in the U.S., Europe and Africa will be able to witness the moon be completely eclipsed by the Earth's shadow. The show starts at 9:45 pm ET but starts getting good around 10:03 pm ET. The next Lunar eclipse will be on Nov 8-9 this year."
Is it coincidence that the Matrix Reloaded is coming to theatres on the 15th? I think not!

I think most of us will be doing something else on the 15th
remember that you do not need a long exposure time. Of course you will need a really long lens.
The first time I photographed the moon I tried long exposure times, in the range of 2-8 seconds when the film returned the moon was a bright white blob with no detail. The moon is basically a rock that is being hit by direct sunlight and to get a good exposure you need to expose your film as if you were shooting a snapshot on a bright sunny day.
One guideline I find helpful is the "Sunny 16 rule": For a subject in direct sunlight set your f-stop to 16, and your shutter speed to closely match the speed of your film. Eg ISO 200 and shutter speed of 1/250.

It also has details for future eclipses.

There is also the loony f4 rule for shooting fullmoon lit landscapes. Set the aperture to f/4 and open the shutter for 1/ASA days. ie 100 speed film =1/100*24*60 ~ 15 minutes. Shoot a landscape 1/3rd + 2/3rds sky without the moon, then double expose with the eclipsed moon somewhere in the sky
There is no moon! ;)

Why is it that Africa and Europe are mentioned, when all of Europe and most of Africa will only be able to see part of the eclipse, at moon-set; but South America is not mentioned at all, when most of South America will be able to see the entire eclipse, weather permitting?
Do not confuse duty with what other people expect of you; they are utterly different.Duty is a debt you owe to yourself.
The phrase "inconstant moon" appears next to the picture in the linked article. If you've read the classic Asimov short story with the same title, this is the last thing you'd want to see. Go read it.
