Hi Lee. The sub length was based on keeping too many stars from saturating while still getting some reasonable SNR on the galaxy. The number of subs in each colour was what the clouds allowed. Have yet to go the G2V calibration route - probably need to look more at a proper colour calibration process. What do you do? regards ray
