Hi,

first of all a great thanks for making life much easier with indilib and EKOS! It's amazing how quickly one can set up telescope automation with it.

I connected an old Meade ETX90 w/ Autostar to a Raspbery Pi 2 with built in PiCamera v2 and soldered on alt/IMU chip - and everything got recognized nearly without any trouble.

Now for the testing I used a distant clocktower @daylight and everything went well, video-wise. (grayscale, full chip, but with 2x2 binning)

But at the first night test I saw that the light collection of the chip is too low, even with 10s exposure - the max value for the PiCamera.

So I tried to increase binning to the max value of 4x4, but that didn't seem to change anything.

Next step was to increase the ISO value. But - the ISO pulldown in EKOS is greyed out / disabled. (see screenshot)

In the "V4L2 Options" tab there is a "ISO Setting" [ Manual | Auto ], which was set default to "Auto". I tried "Manual" as well (with restart of indiserver inbetween). But the problem remains: The ISO-dropdown in the Capture tab is always disabled.

Does anyone has a suggestion / idea / solution, how to change the ISO setting?
(Or how to get more image signal any other way - software-/driver-wise)


Thanx in advance!
