Unbelievable : IT WORKS ! Thank you so much for your help & reactivity.
I did exactly what you mention:
- rename libASICamera2.so.1.25 to libASICamera2.so.1.25OLD,
- copied the libASICamera2.bin (from github.com/indilib/indi-3rdparty/libasi/armv8) and rename it to /usr/lib/aarch64-linux-gnu/libASICamera2.so.1.25
- checked that strings /usr/lib/aarch64-linux-gnu/libASICamera2.so.1.25 | grep 1," gives "1.2" (yes, it does)
... and test Kstars: all ASI cameras work fine.
You're like magicians - thank you so much.
I'm now ready to observe again tonight. One day, I'll show you in detail what I'm doing (spectroscopy with UVEX instrument)...
Take care!
Best regards,
François
