Hi all! My first post here and hoping to be able to get this issue resolved. I am having an issue with my Nikon Z6 DSLR and the Capture module. I am able to take preview images without any issue, but as soon as I try to run a capture job, even if only one exposure, KStars crashes when downloading the image file. I tried a few tweaks to the Frame Image Settings and CCD Info width & height - but the results are always the same. The Preview images are around 146 MB each.

According to DigiCamDB.com the Nikon Z6 specs are as follows:
Sensor Resolution = 6062 x 4041
Max Image Size = 6048 x 4024

ekos seems to want to default to 6064 x 4040.

I have tried all 3 variations without any impact to resolving the issue.

Included in the zip are multiple log files & the DSLR test output. I intended to also upload the sample preview images that I saved after they were displayed, but even zipped it exceeds the file size limit for the forum.

Each of the log files has something similar to this at the end:
