ok, 355mm... hmm...
you don't need Miltons approval to do this, provided his software lets you put the gain register into "absolute value" mode then you can manually enter gain values up to 36 db :-)
The gain is applied directly to the a/d stage, so there is a point where it will reach maximum useful value, but this depends entirely on the camera and ccd, and it's s/n. It's not correct to state flatly that 24db is the limit.
