I hesitate to determine the blur horizon on my differential.
if I push it at a distance of more than 45 cm then it is difficult for me to use the smartphone.
but if I push it just 45cm down I’m afraid I will reduce it too much.
i don’t have a laptop or a computer to work with
Are there any of you who have had success when reducing differential at a distance of blur horizon that is closer than 50cm? like 45cm, 40cm
