Unity gain for 178mm cool??

bergenk

Hi Im using the asiair pro and wanted to check what unity gain should be for the asi178mm cool? According to your site 0 gain =1 ADU??? Is this right? My asi 183 is 111gain for unity. So 1 ADU =111gain.

In the asiair pro there is a tab for a low and high setting only although i know i can use the slider for the 178mm.

The 183 has a low, med and high tab, with the med tab setting unity gain.

Thanks
