Trevor, as Greg says the gain values are different on the QHY from the ZWO.
Useful gain values might be 5, for maximum dynamic range (if you’re imaging at a dark site) and 11, which is unity gain. Maybe 20 for narrowband, but the DR gets a bit thin up at that gain.
Folk seem to use offset 30 with the QHY, although I’m uncertain of the maths behind that.
