Thanks guys - I will definitiely add it to my check list!

I like autofocus aid in APT - so I will try that - is there a video that shows you how to store your results per filter Mark?

So if I find the focus relative to say the Luminance filter for the other six filters - is it simple to tell either ASCOM ZWO filter wheel - APT or SGP what offsets to use for each filter?

Thanks, Matthew
