Beren,

You can fix that using Curves in say PS,

On another note: I think the LPI is perfect for planetary... if folks aren't getting decent shots with it, it's because they dont know how to use it properly. Personally I dont like the the modified TuCam approach. They always give the planets the appearence of a boiled lollie. But that's just me, I like the LPI because it gives a more natural result.

Regards
