So far I have not used any focusing in indilib since I focus manually using liveview on my DSLR and a Bahtinov-mask
Now, waiting for a ASI294MC Pro camera, how do I focus with that camera since there is no liveview?
Can I use the focus-module with the ASI294 in a manual way?
As have been said, you can use the loop function in the "Guide Control" tab. But a neat trick I found is that you can switch cameras in the drop down. I can now use my Bahtinov masks for both the main camera and the Guide camera. Just change the drop-down Guider camera in use. Just remember to switch back to your guider camera (and don't forget to take of the masks... I've never forgot that, haha, yeah right)
I use my Bahtinov mask to get close. then the rest of the night use the focusing module. Because my filters are of course different focus values, I just use the Bahtinov mask for the Lum filter (or whatever you use as the first filter) and then let the module find the rest of the values. Then put the offsets in the "Funnel" icon and let the focuser change the values as my filters change.
