Cordial greetings to all and a new year full of good projects.
Although I have read about the possible solution to this problem from the experience of several here on the forum always ready to collaborate. well I would still like to try a solution , which among other things I know probably lead me to disaster!!!.
On the other hand.may be possible some possible updated solution.
I just bought these objective Zeiss and although they give relatively acceptable images, the images certainly look without contrast.
It is possible to try some of the solutions that we know, as would be to dip it in some kind of solvent xylol for example, or try immersion oil.or give it a little heat to see if they recementan.
I leave some images for assessment of the problem and in advance thank you very much.
