Cheers Steve. I've got a G2V data base loaded in sky so it's a no brainer to snap a few shots off. I have already done the RGB filters but didn't think about Lum. In retrospect, I'd imagine it should be a 3:1 ratio as RGB is additive?
[edit]
Yes it's additive. I got 45K for L and 27K, 25K and 17.5K for RGB but only shot one 5sec sub on a G2V for each.
