@Ante_Vukorepa et al - I’ve tried and tried to take decent shots of the spot convergence and then divergence over distance, but it’s just not feasible with my nexus 5 camera (I did try “manual camera” app which is awesome, but even at v fast shutter and adjusting ISO, shots still blown out)

So I went back to the UV sensitive paper I used back in the day for tuning my replacement galvos on the original F1 - and I think it’s worked out ok - I think the spot convergence and then divergence over distance is shown well - see below

setup:
