Im just a little confused if your just begining in this hobby or you have done it for a while as a star test im still getting my head around what all the different patterns mean and im learning very quickly what it all means because its the only tool i have for getting everything spot on for astrophotography. and are you using a barlow to magnify the star to see the airy diffraction rings?
I just follow this simple rule as a guide: F/5 use a 5mm eyepiece, F/10 10mm or similar. Defocus slightly on both sides. Out focus always looks better than in focus for me.
