Hi.
I'm using INDI drivers for my asi1600mm-c. The INDI driver uses the settings reported from the sdk, but there are no Unity or Offset, only Gamma and Brightness. How are these properties translated. Is it the same settings renamed or does the linux sdk vary from windows? When googeling this camera setting are always reported in Gain, Unity and Offset as most users uses windows.

Would appreciate some clarification.

Thanks in advance, Magnus

offset = brightness
our SDK for Linux is same as it for Windows, but what does your Unity mean, we don't have this setting

Hi. I asked the question about unity here https://stargazerslounge.com/topic/2687 ... nt=3123271

Apparently it's the gain setting of 139, so a therm and not a setting.


Unity gain refers to a Gain setting of 139. It's the value that produces 1 ADU per electron. Doesn't mean very much in practice except that no extra dynamic range is obtained by going below a gain of 139, as I understand it.


This results in Gain = Gain | Brightenss = Offset | Gamma (apperently a camera setting that is not present in ascom). From what I understand Gamma = 50 is the default (neutral) setting.
