Will give it a try tomorrow:-) 

 

If I remove the lenses from the cell, is there anything special to consider with reattached them back into the cell? I assume there are pretty much in a fixed position, so adjustment isn't necessary afterwards. 

 

Thank you.

Do not try to remove the lenses from the cell! Don’t touch that retaining ring!

Managed to remove cell from tube. 

 

How do I loosen the outer ring? 

Clean the outer surfaces only and put it back together.

I agree with not taking the lenses apart for cleaning. The dirt would have to be very bad if this was required.

Even after taking apart and cleaning, you could still end up with smear marks from the cleaning process.

A few marks in-between the lenses will have no effect on the performance of this lens.

 

Usually you would take apart the lenses when doing specialized work.
