Hello, I am a newbie here. I recently got some of these binoculars but the collimation is off. I Sent them to Nikon service centre, who have said that they can't sort this due to not having parts. They offered me 20% off a replacement in return for recycling them as the warranty is now out. Surely this can't be correct that they can't be collimated? Also this model is still for sale on Nikon website so I'm not convinced that parts aren't available. Anyone have any suggestions? Many thanks
