Hence the sky map.
Besides, who knows if this clear sky will last ?

Thanks for showing us the result with just the UVIR cut filter Paul. By the looks of it there is very little difference between the two in terms of nebulosity and detail revealed. I'm just surprised that the UVIR cut filtered one didn't show more star colour in this region but perhaps 120 second subs has overexposed the stars in a dark sky. Like Martin said, a near full moon is going to play havoc on colour balance. Either way, a true comparison would need to involve identical conditions, preferably conducted on the same night and the captured data processed using the same workflow. You were definitely lucky to get another clear night to experiment and taking advantage of that is what you have to do at the moment with the way the weather is.
