Hi, I use a Fuji X-T2 with Kstars/Ekos/indi. The driver has some limitations but it does work. Driver configuration points:

• Leave the camera in T mode and only use exposures from the preset list - Bulb mode does not work properly.
• Set the SDCard mode to Delete - on the Fuji this seems to control the RAM buffer usage as well. If you don't set this to Delete, the camera will take shots until it's RAM buffer is full and then hang. Note this also means that the images are only saved via indi (to your computer) not to the SDCard.
• I set the Transfer Format to Native (RAW) not fits because on a Raspberry Pi (I'm running a RP4 8GB) the 'bayer' decode of the funky Fuji X-Trans CFA takes too long (10's of seconds). This means you can't run the fits viewer during capture. Image display for other functions eg. focus, plate solving alignment, PA work fine as they use the image un-debayered. Also note that the Transfer Format setting does not seem to get saved in the Capture module or passed from the indi driver settings - you have to set it each session in the Capture module.
