"Blood Moon" Calendar for Americas

http://www.cnn.com/2014/04/11/tech/inno ... ?hpt=hp_t2

four times in next eighteen months starting 14APR2014. Calendar and description in article.

this coincides with a lunar eclipse April 15 Most in North America should be under the eclipse
wishing for clear skies.

still minus 32C LOL

Any "easy" suggestions on how to expose for the moon during this time? My brain is hurting from trying to make sense out of some of the online guides!  

Thanks,
Robert

Dang it, predictions are for a very cloudy sky over Long Island tonight

Can't wait to see some posts of this event!

Only clouds and snow here tonight. So no chance for photos. The Snowmageddon winter continues!

Exposure times for a full moon, uneclipsed, run about 1/500 second f/10, iso 200 to 4 seconds at f/5.6 iso 200 and longer for a fully eclipsed moon (which means one needs tracking if using a telephoto lens).

Sunny 16!

George, the reflectance of the Moon is about half that of the Earth, so a better rule is Sunny f/11.

For anyone not familiar with the rule, it is exposure time = 1/ISO at the f/ratio, so:
Earth sunny 16, ISO 100: 1/100 at f/16 (bright sunny day (not sunrise or sunset)
Moon sunny 11, ISO 100: 1/100 at f/11.

But as the moon goes into eclipse, the exposure times get longer.

Absolutely, just a ballpark starting point but thanks for the clarification...

I retrieved the lunar eclipse data from http://www.mreclipse.com/ . Exposure data and other info is:
http://www.mreclipse.com/LEphoto/LEphoto.html .

I downloaded the .pdf for the 15APR14 eclipse from this calendar by clicking on the date link in the left hand column:

http://www.mreclipse.com/Special/LEnext.html

which gave me the time schedule window for the various phases with an illustrated image of the shadow phases.

The description of the Danjon scale is here:
http://en.wikipedia.org/wiki/Danjon_scale
needed for the exposure table.

The next is:

with the greatest phase at about 10:55UT. In my time zone it is about 1.5 hours before sunrise and and almost coincident with moon set at 18 degree elevation using TPE:

which is freeware for the desktop and low cost payware for smart phones - a very handy application for showing sun and moon direction and timing from a coordinate you find in its gmap background.

I missed yesterdays because it became mostly cloudy and I tore down my setup about an hour before. I did find out, tough, that I need to do a work around for the high elevation of 37 degrees like reverse my camera/lens mount on my head since the tilt handle encountered the head and adjusting the tripod legs to compensate would risk too much imbalance. It also was a little unseasonable at 27F at 3:00 am local. The October elevation will be 18 degrees and I could have obstacles.
