First picture: I put the sun just behind the neighbouring planet's atmosphere, then I got this purplish coloured eclipse:)
Second picture: TG is good at simulating the Martian sunset(bluish sun because the different atmospheric light scattering
Third: Fisheye planet! Sadly there's a maximum fov,so the sides are not quite there.
Fourth : eclipse from the other side of the Planet-moon
Fifth: a crop of the previous image -I like the composition
