ASI2600 Gain Preset ASCOM Driver

Hi;

I need clarification.

I understand that ZWO decided to limit the range form 0 -100 on the ASCOM driver. 100 been the unity gain and where the read noise as low and regaining some DR.

BUT, when I select "unity gain" on the ascom "ASICamera Set V6.0.3.28", I get a gain of ZERO under the camera setting.

When I select Lowest read noise, then it goes to 100.

What is unity gain (pleas dont tell me 1 eADU :) ). on the gragh?

I'm so confused about this, I'm thinking of returning my 2600....

You could see the graph, the unit of gain is dB, it means when you set a gain of 100, it reaches unity gain. At the same time, the GAIN is 0.25e/ADU.
