In the first shot the moon is massively overexposed. In fact it looks like the sun taken through a dark filter. In the second shot the moon shown (Enceladus) is also overexposed.
It's a very long way from the sun compared to our moon, approx 1 400 million km compared to 150 million km, so it's very dark out there. Enceladus has a very bright surface, but given the distance from the sun it still takes a very long exposure to overexpose it.
Ignore anything straydog posts, he's an idiot and it's not worth trying to debate with him.
