Holy Cow Aanker, that's ludicrous!
Here is the ridiculous shot from Dutch Harbor that started my whole investigation. Here we have a crescent moon in contact with the setting sun in the sky. There are many, many problems with this rendering.
Perfectly obvious is that the moon is rendered half or maybe even a third the size of the sun. That is completely false. They are both almost exactly the same size in the sky due to an amazing coincidence. In reality the sun is almost exactly 100 times larger in diameter than the moon. But its distance is also almost exactly 100 times further, making them look identical sizes in our sky, not one three times larger than the other as rendered by the "close enough for me" SH4. Because of the non-circular orbit of the moon it gets much less than a tenth of a degree larger or smaller than its nominal half degree size. The earth's orbit around the Sun is nearly but not perfectly circular, so the sun also changes a tiny amount in size depending on when you look at it. We're talking about tiny, tiny differences, never even detectable unless during an eclipse. For all normal purposes, they are identical in size, subtending almost exactly one half a degree in angular size. In this regard, SH4 can't be called "close" unless you are laughing while doing so.
The second error in the screenie is the phase of the moon, which leads to the third error, the setting time. Most people don't realize that the phase of the moon directly tells you its setting time! For instance, a 3/4 moon (that's half lit) is always straight overhead at sunset. Since it is straight overhead at 6 pm astronomical time, that means it is three hours behind the sun and can't set until 9 pm. The moon in the screenie is about 1/8 phase. That means that its position is wrong and should be rendered a quarter of the way between the zenith and the sun. That is the ONLY position where the moon can show that phase. This would shift the setting time to 1/8 of the 12 hour daylight period or one and a half hours later than SH4 will show it. Is an error of an hour and a half "close?"
If you want to chase the rabbit of "the moon is rendered in the right place and the setting time is accurate" then you have forced SH4 into another error of showing the moon at completely the wrong phase. At that position the moon would be new, with no lighted portion visible at all. You would be totally unaware that the moon was in the sky without an almanac or having followed it from previous days when it was visible.
I haven't even barked up the tree that the original poster told me the date represented and that it was the date of the animation I have already posted in this thread. Since it was the day of the eclipse, we know the alignment of moon and sun. At sunset it would have been after the eclipse and the moon would have been invisible, but to the right of the sun, not above it and slightly to the left.
So SH4 doesn't get close in any aspect of the screenshot. Fail, fail, fail, fail. In what way can that be "close enough" unless you just don't care when the setting times are, what size the bodies are, where they are depicted in the sky and what phase is shown?
Silent Hunter 4 is not a solar system simulator and wasn't ever meant to be. Trying to hold it to that standard is ridiculous. We see a sky. That is about as far as it goes.
