|I have a Tair-3 Phs with dirty elements. I've managed to remove the optical block from the main body, and I've removed the front element, cleaned that successfully, and replaced it. But I'm having trouble getting at the rear element(s) and I'm not sure how to gain access. Set down inside the barrel is a very, very tight retaining ring. I can just about move it with a lens wrench, but there's a lot of thread in the barrel and I want to make sure I'm doing the right thing before I go ahead and remove it.
Does anyone have any experience of cleaning the rear glass on the Tair-3 models? I would be very grateful for some pointers!
Many thanks in advance
