Sorry for my ignorence but can you tell me what difference it makes to imaging when you lower the refresh rate i.e. make it quicker from say 1.5 to 0.02? I've noticed this setting and you are right, I had mine at 2.00 I think. Everytime it beeps I panic and try and realign the tracking
Your image looks great!
Cheers!
