Thanks Marc, the ESATTO Motorised Focuser, @Focus3 in The Sky X Pro and PixInsight have awakened me from a deep DSO slumber.

I had become a bit disillusioned with focus drift problems and marching noise across my frames (I never dithered), but now I have discovered the delights of injecting an @Focus3 run into my series, dithering between frames and processing in PI, my enthusiasm is renewed.

Cheers
