I did try removing Sony DSLR Alpha-A77 M2 (Control)_config.xml in ~/.indi, this did not seem to have any effect - when indi connects to the camera, image size reverts back to 6058x4012.

I also tried manually editing the config, and found

<newNumberVector device="Sony DSLR Alpha-A77 M2 (Control)" name="CCD_INFO">
        <oneNumber name="CCD_MAX_X">
6000
        </oneNumber>
        <oneNumber name="CCD_MAX_Y">
4000
        </oneNumber>

<newNumberVector device="Sony DSLR Alpha-A77 M2 (Control)" name="CCD_FRAME">
        <oneNumber name="X">
0
        </oneNumber>
        <oneNumber name="Y">
0
        </oneNumber>
        <oneNumber name="WIDTH">
6000
        </oneNumber>
        <oneNumber name="HEIGHT">
4000
        </oneNumber>
    </newNumberVector>

Changing the dimensions to something smaller than what it changes to on it's own, say 6000x4000, in indi control panel at least keeps the resolution constant from one frame to the next, but this setting resets every time the camera is disconnected and re-connected. How can I make the image size setting persist?

So I'm assuming the current stable version is in kstars-bleeding, despite the name. I removed kstars and reinstalled with the more recent version from kstars-bleeding.

Testing with KStars 3.6.9 Stable, I added two identical jobs to capture one light frame each as fits - and they do come out with different dimensions, 6024x4024 and then 6024x4012.

Starting ekos and connecting to camera, image info in indi control panel says Max Width is 6058 and Max Height is 4012. After capturing a frame (at 6024x4024) numbers in indi control panel change to 6024x4024 - and size in ekos capture settings changes to 6024x4012, which will then be the resolution of the next captured frame...

Interestingly gphoto2 --capture-image-and-download gives me a .ARW reported by darktable to be "6022 (6048) x 4024" when it just says 6048x4024 for my regular photos (taken the usual way without tethering)... I don't even know

I had the same experience trying to recover a lost password; the email never came. So I made a new email and a new account, the activation link for that came through just fine.

Hi all,

I'm getting back into astrophotography after a long hiatus, so I have a lot of catching up to do. In the past I always took all my frames in dslr raw to camera's memory card with a wired intervalometer. Now I got kstars/ekos running and tried saving as FITS to laptop hard drive and I noticed only after the fact when I tried to calibrate my lights - some of the pictures have different dimension. Some are 6024x4012, some are 6024x4024. For my usual camera raws the resolution is always x4024.

In the log file I find the following;
