How do you objectively compare resolution of binos & spotting scopes?
I’m thinking I need to put up the USAF resolution chart and look at it compratively through each instrument straight on, at angles, and under different lighting conditions. I don’t know:
1. How far away to put the chart.
2. How to compare resolution for high or low contrast objects.
