Dennis, there's a very technical reason for capturing in BW... I'll try to explain it in simple terms...
I forgot to uncheck it after imaging the moon on the previous session... (I didn't even notice until my last avi of the night - I was using a red screen filter so didn't notice the lack of colour as it was captured either)
I find as I get older I'm doing more and more stupid and embarrassing things... I hope I don't wear out my sense of humour... that would be sad! I console myself by thinking about all the young sharp minded dudes that this will also happen to one day!!!
Al.
