Hello ZWO,
ASCOM Driver and SDK (INDILib) return different images with ZWO ASI183. With INDILib (SDK) there a two additional glows below right and left. With ASCOM not. There must be an difference. In the attachment, there are two masterdarks made with the same camera, temperature and exposure time. Can you modify the SDK in that manner, that the glows return.
