Hi,

I have a ZWO ASI6200MM full-frame camera with maximum resolution of 9576x6388 pixels.
When I use this full resolution in 16-bit mode, KStars does not display the image.
Images with these settings are around 122MB in size.
I test this from the CCD window. In the CCD windows it keeps saying "Downloading..."

When I use hardware bin 2x2 in 16-bit at this full resolution it works correct (this reduces the file size significantly)
Also, when I use 8-bit mode at the full resolution (so without binning) it also works correct.
When I use a resolution of 7680×4800 in 16-bit mode it also works fine.
Then when I change again to 9576x6388 16-bit it again does not work anymore.

I played a bit more around and discovered that when the file size becomes 100MB or larger, the image is rejected (by INDI or KStars, I don't know exactly).
A resolution of 8000x6200 pixels in 16-bit mode without binning still works, but 8000x6250 (now the file size becomes larger than 100MB) does not work.
Is this a known issue? I'm not sure whether it's INDI or KStars causing this issue.

I run INDI server on my Raspberry Pi 4, and I run KStars on my computer with Debian Linux.
Raspberry Pi and computer are connected to the wired network (Ethernet).
INDI version = INDI Library: 1.8.9, Code v1.8.9-1-g4c3f1c60. Protocol 1.7.
KStars version = 3.5.2 Stable

Thanks in advance for the help!

Kind regards,

Sander
