Finally got a clear night

be it a bit windy , tried some capturing but the images did not come out well at all, out of 6 captures only one half decent is the attached moon pic, ah well tonight looks like it going to be great
I want to put this out there as I don't know whats going on, Ive only been out with the DBK21 twice since I got it and this has happened both times, when I do the first capture the AVI is colour but all other captures after that are black and white

I have not changed any settings from the first capture so don't know why?
I'm using IC Capture 2.1
Anyone got any ideas.
Cheers
