I bought a ZWO ASI185MC and I get strange FITS frames with INDI on a Linux laptop and on Raspberry Pi. When I use SharpCap on Windows, the frames seems to be okay. I played with exposures 2-6 seconds, varied the settings back-and-forth for an hour, the end result seemed to be always bad, sometimes just black frames. I attach two samples.
I do not have that particular camera, but have seen issues when the bandwidth parameter is set too high. What is yours set to in the camera control panel?
In looking at your images again, the first one looks like a bright reflection, like a neighbor turning a light on. The second one is a problem I see on a rare occasion as well with my 1600. It hasn't happened enough to cause me a lot of grief, and seemed to happen even less when I turned off the auto-bandwidth checkbox. How often is it happening for you?
Thanks for the suggestions.
Always happens, but now I looked into the statistics and the pixels of the "glow" effect have very low intensity. This seems to be normal, it just looks weird because of the auto-stretch function of the FITS Viewer in KStars.
