Hodilo by se o tom jiste napsat clanek, ale mam ted jine nalehave psani.
Aspon jsem to vyfotil, vyhodnotil a anglicky popsal. Je to trochu jiny

You may like to glimpse onto a colourful summary of lunar eclipse I did
mostly just as an illustration of my imaging photometry method.
It's an 3.5 MB file overview.htm (with all the thumbnails are loaded)
within    http://amper.ped.muni.cz/light/luminance/lun_eclipse/2006

Ratio of luminances of the lunar rim in umbra and the opposite one is
1:1000 -- one candela per square metre in the earth shadow, and one
thousand cd/m2 at the almost full-sun side. Toward the end of eclipse,
maximal luminances are just over 4 kcd/m2.

The directory gives also an example of how the SQM measurements match the
imaging photometry
(I took the effective space angle of SQM to be whole 2.2 srad).
