rear element could be removed. and also the other ones.

-as well as their professional correct alignment. I wonder - was it worth, image-wise?

Pfsor, it isn't clear whether the OP finally figured out how to unscrew the cells from their barrel or how to open a cell.

It dawned on me that perhaps he doesn't know the difference between lens elements and groups but then I took it as intended in the common optical nomenclature.

You can't be sure with this poster. Its wonderful that he tries to communicate with us in English but his English seems to be weak.

I see - that did not dawn on me. Thanks to tell me. Cheers!

It is wonderful. I would suggest that for short posts that people post in their first language, and others here can translate if they wish to help.
