The Lacerta FBC not only regulates the brightness of the FFB, but also the flash time and synchronizes the flat exposure with the camera shutter. An innovation that makes sense! Best with our flicker-free Lacerta flat field box, with sophisticated, evenly distributed white light. The Lacerta FBC can be used in 3 ways: Standalone - with DSLR remote shutter release (or mgen...) via the PC - the software then controls the DSLR and synchronizes the shutter via FBC Autoflat with APT (NINA is in preparation) - automatic measurement and creation of entire flat sequences with all filters
