Think the collimation is very slightly out now though <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /> not surprising as I was messing about with the prisms removing and cleaning them! Think to finish them off I need to find out how the eyepiece optics come out so I can clean them, and should then be able to get the shoulder plates off so I can get the eyepiece-side prisms out to clean them properly too.  Much clearer view out of them now anyway, sharpness is up there with a lot of modern bins!I'm going to give my ZOMZ 12x40s a bit of a clean now, they're in good nick but lenses a bit grubby - with any luck it's that which is making the bins look a bit mis-collimated, though I suspect I'm being a bit optimistic there!</blockquote>
