Hi,
the simple answer is that the best range for the Altair 26M/C is probably 300 to 1000.

Sorry, gain 300 to 1000.
Black level is easy to adjust - set gain, set 16 bit mode, cover camera, set short exposures (<1s) and adjust black level to make sure that the peak in the histogram is separated from the left hand side of the graph.
The black level value needed will depend on the gain, since you will see the peak in the histogram gets wider for higher gains, so you need a bigger black level setting to achieve separation.
