2007 Aug 28: Total Lunar Eclipse
The red colour is due to sunlight being refracted through the Earth's atmosphere - essentially, the combined glow of all the world's sunrises and sunsets.
It is the reason why the Moon is not black but reddish during a total lunar eclipse.
Unfortunately the sky clouded over during the last half of the eclipse so my seqence was not completed.
Taken on a home moded Canon20d thru a 152mm f8 four element Super APO refractor.
Takahashi NJP Temma II mount.
No filters apart from LP front filter.
Taken from Onerahi, Whangarei New Zealand in July 2007.
