Astrometeorology 8, Brahe's Star Castle interior
This is simply an expansion and revision of part 7. At that point I couldn't see how the various instruments were fitted into the domes, and I was wildly underestimating the size of the instruments. So we'll try it again, with a more complete underground structure and more appropriately sized instruments.
First the entire property from front, side, and top, as before.
The square central part was the workroom and residence for Brahe's technician. Fortunately the existing floor plans show a worktable and a fireplace. So I've given Polistra those two items, plus other stuff found in unrelated pictures but appropriate to the place and time. The jugs over the fireplace nicely match Brahe's Persianish architecture.
Another view, showing the worktable. You can also see the stairs up to the adit at the left side of the property.
From the central room, halls branched off into the circular observation rooms. First we'll walk into the Sextant room, which is covered by one of the flat 'sewer grating' domes.
Looking down into the grating toward the sextant:
And here Polistra is sighting down the alidade toward a target star.
Next we return to the central workroom and walk toward the Equatorial instrument in the big dome.
Looking at it from above. The descriptions are unclear, so I've arbitrarily made one pie-slice of the domes transparent. This wouldn't have worked in 1600. Did Brahe have hinged panels, or did he have a crew who lifted each entire dome off when it was time to observe? Most likely hinged.
Here's a closeup of the equatorial in its arena. I had to 'remove' some of the walls to get this angle.
Now you're looking along the alidade toward the pie-slice in the roof.
The Quadrant Magnus occupied the other 'sewer grating', here seen from the top.
And again Polistra is measuring the azimuth and altitude of a chosen star.
