Le Naturaliste

David,

the Ultropak lens is oftenly missing - and more oftenly overlooked. If you look from behind into the UO and you discover a tiny glass plate, you have found that lens. It has not a big focal length because it just has to adjust 185mm to 223mm tube length. Therefore it appears like a protective glass plate.
By the way, it is not a big issue, if it's missing, especially with low power objectives.

Hello Wolfgang,

I found a lense about 01cm inside the UO but it doesn't seem removable (which is not a great concern!).
Thank you for the explanations

Hello

J'aurais bien dit un genre de "Water immersion" (en allemand, ça fait...)
L'ON est à 1,l'objectif fonctionne sans lamelle couvre-objet... ça doit pouvoir coller.

ça fait Wasser Eintauchen
