Cheers, all. On my phone here so, I'll be brief, it's no fun typing on a keypad.

Jack: cheers, blurring the sky would be my usual course too but I'd then lose the stars, which are rendered, not post worked. Jason: the moon is a TG planet with a larger, invisible, weak sun behind it. I used a 'through camera' projected image, rescaled and placed, via the shader preview window, for colour and a little luminosity. That's about it!
