Nice image Michael. We didn't even try with the clouds last night and others have reported that the seeing was very ordinary so you have done well. Certainly, theoretically and from our past experience, the ASI224 needs an IR cut filter to achieve sharp focus. It's only supplied without the IR cut filter in it so that you can use an IR pass filter for IR only images as the RGB responses match each other from around 800nm onwards.
