Just an idea I had but haven`t got all the hardware installed yet. I know I can control two ccd`s with Ekos but can I open another desktop and then another instance of Kstars/Ekos to control a third camera? I would then just switch between the two desktops as needed?.
thanks
Steve

No need, there is a much simpler and more convenient solution: just go to Tools --> Devices --> Device Manager. Then select the 3rd CCD you want to use and click "Start Services". You'll have it added to the INDI control panel along with the other devices you're controlling. If the 3rd CCD is remote, just fill its information in the "Client" tab and click "Connect" and you should be set!

Excellent thanks for that Jaseem!. Is Ekos OK with FireWire type camera's, my DMK is one of those ?
Thanks again
Steve

The camera type doesn't matter as long as there is an INDI driver for it.

Cheers Jasem so I assume there is a firewire driver for Indi?

What I know is that DMK is recognized as a Video4Linux device and therefore you can indi_v4l2_ccd driver to control it.

Excellent thanks for that. I`m just building a tower pc for the obs including firewire so I`ll check that driver out.
