This causes horizontal blooming on bright stars. The blooming can be reduced or eliminated by reducing gain (I think the QSI cameras do this automatically) but that comes at a cost in dynamic range.

Ive not seen blooming with the QSI583 chip at 2x2 binning but I have seen it on very bright stars at 4x4 binning (but even then its minimal).
Im going to set up tonight (cloud permitting) to see what I can do on NGC1398 and will have a play with some parameters.
