Hi all,
I have had a night with good images of the rosette nebula (a nice mosaic!).
Later in the night, Kstars crashed more often than usual, so I figured: let's reboot.
Didn't work: boot. Looking at it with a monitor attached to the hdmi, I see the Stellarmate 'startup dots' but it doesn't continue from there.
My guess is that the SD card is full, but this shouldn't ever result in a problem, right?

My questions:
a) How can I recover the images? These are precious because of the very few clear nights here.
b) What could have happened? How can I prevent this from happening again?

Stellarmate 1.6.0 on Rpi 4B 8Gb.
64Gb SD card Sandisk Extreme Pro.

Thanks a lot!!
