Cheers mate.
It's probably what I'm after.
I'm looking for the sky bitmaps that go with the GPxPatch settings under GPxSet (Sky bitmap prefix drop down list).
I've got Skya and NightSkya.
I was just wondering where to get the SunsetSkya
I notice the ones you've given have the same names as the Night Sky set.
I suppose I just rename them with a sunsetsky naming format?
