I've been making objective dust caps.
The slightly smaller black one is for the cell when stored in the box.
The work in progress is obviously for the dew shield.
One of my pet peeves are telescopes that store without their dew shields and no lens cap is provided.
Counting this one, I have four like that.
I'll explain my secret exotic composite technique sometime in the Soligor thread.
The Rustoleum semi-gloss black sprayed so nice it got me thinking of restoring a couple of the eyepieces from the Penncrest,
but now I might paint them different colors like the ones from Sears.
I'll probably never use these, but I want the kit to be complete.
