Auroras

Sunday night was high solar storm, but also cloudy.  Monday night was clear but more subdued.  Mostly gray or silver; very little of the other colors.  Plenty of  shimmering and moving curtains.  Some okay pictures.  One 8 second exposure was okay, but 30 second exposures did much better.  One picture even has some pink!

Time lapse to make videos is clearly impractical.  For every second of exposure, there is a second of dark frame exposure.  To do this properly means either a large aperture lens or multiple cameras in parallel.

The K10D only goes to ISO 1600.  The K30D goes to 51200.
