Greg,
Imaging with newts eliminates the need for me to use a bahtinov mask
I just slew to a mag 2.0 to mag 2.5 star in the region of my target or its mid elevation path, take 20sec exposures in APT ( adjusting the histogram accordingly) and tweak my ZWO EAF electronic focuser until I get super tight sharp diffraction spikes on my Star.
Usually only requires 3 or 4 tweaks until I’m happy or around 5 to 10 minutes
So basically software assisted eye balling
Works for me every time unless atmospheric conditions deteriorate or are crap then focus usually drifts anyway whichever method you use
