All that will become (?) easier when a freeware version of Roddier will be
available... in short you take pics of your defocused star at different
offsets, and the soft analyses the wavefront for you. Though as often, I
guess having a soft does not make unuseful to still be able to perform a
"manual" star test :-) Which I am not acquainted to yet.

Clear skies,

Hugues
