That is a very good shot, the fainter details are starting to show nicely. This is a faint object to capture so well done indeed.

Presumeably the shot was with the QHY8 via the VC200L (FR) or was it with the 40D? BTW as a Dark contains the Bias and you subtract that from the lights during calibration I did not think you needed to use stand alone Bias for processing unless you want to get a scaleable thermal frame to use with different length exposures. (aka Adaptive Darks).
