Two days ago I made the sudo apt-get upgrade. When I went for a imaging-session yesterday, the asi driver for the zwo asi 2600 mc-pro suddenly offered a maximum gain of 700. The maximum gain should be 460 due to the manufacturers documentation. Will the camera behaviour be the same as it was before when I set the camera gain to e.g. 110?
Anybody any idea? Before I upgraded, the maximum gain was 460 as it should be. Has the ASI-driver changed? In which way does the change effect imaging performance?
Thank you, Jasem. I wrote an email to zwo support. They say
"It is normal, the gain over 460 is digital gain.
Gain range may differ from software and drivers."
They couldn't tell, if the driver has recently been changed.
From the camera's bahaviour I would say there is no difference between before and after the change, i.e. gain 110 leads to similar images as before.
However, it would be good to have an explanation, why suddenly there is a different maximum gain in the driver … that is not a thing that happenes just like that.
