I picked up an old pair of Hanimex Explorer 8x30 bino's for $5 at the school fete today. However they have a slight
collimation problem.
Looking at the moon tonight I see two images with clear separation between them.
Is this too far out to fix by adjusting the collimation screws on the prisms?
I've search the Internet and found some instructions but they sound like they apply to minor collimation issues.
