So far, from the two relatively short testing sessions that I have conducted, my impression is that Pavel’s mask seems more “certain” and “absolute” compared to the on-screen example I have just looked at on the Ron Woadski link provided.
My Mewlon has a 3 vane spider and so all bright stars have 6 diffraction spikes without any mask. Although these diffraction spikes are a very useful aid in getting a good focus, I can still “dither” with the motor movement keys and “interpret” the “best” focus using the built in 6 diffraction spikes.
When I fit Pavel’s mask, I experience something quite different. There is no dithering or interpretation; the spot of best focus just jumps out due to the “moving bar” being located between the arms of the shallow X.
Note that here, I am comparing Pavel’s mask to my “native” diffraction spikes as I have not used the Wodaski Mask and Method.
Cheers
