Saguaro Blooms and Stars

A startrail photograph was taken over a blooming saguaro cactus of the north-western sky over Phoenix, AZ. The composition was made of 110 fifteen second exposures (Canon t2i - Canon 17-40L zoom at 21 mm - ISO 800 - f/5.0) Three exposures were taken at the end using some light painting at f/22 to sharpen the details. Images were stacked using startrails.exe program.
