If you change the center by 12 hours, the display bounces wildly for a few seconds before settling down, instead of moving smoothly.
To reproduce:
- Go to the page
- Change the Center field to 0 h
- Change the Center field to 12 h
Observed behavior: The image flickers and jerks around for a few seconds
Expected behavior: The image smoothly moves to the new position. This is what happens if you move to, say, 11 h.
This is reproducible and happens with different projections and different 12-hour shifts. The same thing happens if you change the center angle from -90º to 90º.
The cause is probably that a 180º rotation can be interpolated either way, so half the stars go one way and half go the other way, causing chaos.
(I'm not sure if this project is still active, but I'll file the issue for reference.)
