Hello everybody. I have a Meopta Opemus 6, but I am having problems with the alignment since the image on the easel is not a perfect rectangle. I would like to know if someone has had this problem and how it was solved. Adicionally, I have read that there is a device called Versalab Parallel (http://www.versalab.com/server/photo/products/parallel.htm) that looks interesting, even though it is expensive. Can you give me some advice? Thank you. Henry.
