This shows the gain relationship for the different cameras - The first column is the gain amount in simple terms - ie how many times brighter is it than the lowest gain. The dB value is just 20*Log10(gain). The other columns show the values that the different cameras use for the listed gains - two columns for QHY as some cameras use one set of numbers and some the other.

cheers,

Robin

On a par with your bias effort ;)

Thanks for the table. Now dB = 20*Log10(gain) I can understand.
