I haven’t noticed the veiling glare on my fixed 10 but it’s been used mostly for squirrels on my 17hmr in the middle of the day. I’ll have to see if it does it. I’d have a hard time believing it’s worse than the Schmidt Klassik I had. It was downright unusable at dusk/dawn if you zoomed past about the halfway mark.
Try a backlit hillside at sunrise or sunset.
