Hi, I have finally found some time to update overlay to current version, which is of course 1.8.3. All the new drivers have been pushed into the overlay's tree. Before update, use
emerge --clean sci-libs/asi-common sci-libs/indilib-driver-altaircam net-wireless/lime-suite sci-libs/indilib-driver-toupcam
--update --deep --with-bdeps=y
