Thanks Lubachl.
I used Adobe illustrator as it gives a bit more control over the placement of lines, then printed out the image and measured the angle.
The veho is fairly cheap, I believe the dynolite has some software to enable the placement of measurement lines.
I had to remove the clear plastic cowl around the lens on the veho to be able to get the scope close enough to focus. I think this also necessary for the dynolite.
It is very fiddly to position the scope relative to the stylus to get a good image. Time and patience required in abundance. A longer working distance might well be an advantage.
