High!

Meanwhile, I managed to add a random starry sky_sphere based on the 
object pattern to my Ghurghusht/DM +19 279 system project, with four 
brightness classes of stars appearing at different angles of the sun (i. 
e. DM +19 279, known also as Shams by the locals) below the horizon.

But I'm still not content with the appearance of the sky just before 
sunrise/after sunset: instead of smooth brightness transitions, I get 
patchy, streaky structures (see images attached here). Also, bright 
spots show up on the hillsides long before the sun is close to the 
horizon. And I wonder what makes the water (gleaned from Christoph 
Hormann's pages) reflect a blue sky even when it should be as black as 
pitch...

The "sun" positions are as follows (from first to last image):
79, 20, 16, 12, 8 and 4 degrees below the horizon
