Here is a high dynamic range combination I came up with using two sets of 20 exposures (total 40 exposures). One set for the earth shine side and one for the sun shine side.
Taken from my backyard in Byron Bay NSW, Australia Jan 24 with a Celestron 9.25″ SCT w/ Focal Reducer (6.3) and Canon 70D. Backyard EOS, AutoStakkert & PS6 software used for capture and post processing.
