Hello Jasem, thank you for your reply.
Is it possible though that there is a bug in the QHY driver or QHY SDK as of INDI Library v1.7.6?

- Before the update to INDI Lib v1.7.6, Streaming / LiveView in Kstars / Ekos were available
for my CCD-Cam QHY8L-C
- With regard to the release message for the INDI Library v1.7.6, both the QHY driver and the
QHY SDK (from v4.0.1 to v4.0.12) have been updated
- My CCD-Cam QHY8L-C explicitly supports the Live View mode (Spec, Manual, Capture Tool
EZCAP, please see my snapshot image)
- Also the QHY-ASCOM-Driver supports Live View for my QHY8L-C
