The 183 has very low dark current, so typically the shot noise is higher than the dark noise.
So far, I've resisted the temptation to go below gain 50, as below that quantisation noise becomes an issue...but short subs are the order of the day with my f/4 newt. |

From the ZWO site:
High Speed
Fast FPS can be used in solar(white light) and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.
Notice: depends on user’s feedback, this IMX183 sensor has grid pattern noise when do Ha solar imaging, please take flat frame for calibration(out of focus or add a barlow lens to take flat frames). We recommend our ASI1600/ASI174 mono camera for Ha solar imaging.

Interesting. I suppose that would be the same for similar architecture sensors like the 6200, the 2600 and the 533 cameras. All BSI small pixels.
