IGWT looks doubled pretty good. Or wrong kind ? Traveling so had to take pics in truck with some light so excuse the bad photos please.
I swear when I hit the right angle you can really see every line separating like the coin I used as reference. Is it possible I could be hitting photos at the wrong angle and it not be visible? Or is there enough to know for sure its not? The U really stands out when looking at it with loupe. Not saying you are wrong by any means. Just making sure its not a possibility.
If that's what you are experiencing then I say no to doubling. Light at different angles can cause an illusion of doubling. IMHO.
I have mistakenly seen doubling and have learned to rotate the coin 360 degrees under your scope; an illusion will disappear and a real double will stay.
These images of a '66 SMS Kennedy were taken by me from directly overhead. I am only using them to illustrate how easily you should be able to spot doubling on IGWT. Chris
I've seen stuff this bad and worse and hand been told not dd. My photos are killing me cause I was not getting a squared up image so hard for anyone to help.
Light reflected directly back into your lens will give you false images, the doubled coins referenced above have lighting that approaches from different angles. My family recently bought me a coin microscope and it has indirect lighting, not directly from above and it has improved a lot of my pics. Machine doubling will fool you too, if the edge is hard and step like, it is machine doubling.
