Interesting stats for ASI1600 @ 250 Gain

Been doing some playing around, as I thought I could get sky limited with very short subs (as in 6sec lum*) and high gain on the ASI 1600.

Ran the Basic CCD Parameters script in PI and got some interesting numbers.

Apparently setting the gain to 250 gets me a true gain of 0.269 which is about what I expected, but the read noise is coming in at 1.17x.

* For the record, I now think I was way off with the expected sub length and I think I'm actually looking at about 114s lum @ 250 gain, and I've been underexposing lately.
