A dust cap, it’s one of the little things but it’s job is so much bigger. My order was less than $10.00 but it was handled with as much expedience and efficiency as my last order, which was considerable.
Item works fine, ordering and delivery was great. Thanks!
Very good using a lens caps and it certainly protects the lens very well
I had lost my end cap for my TeleVue 55mm eyepiece. The TPO cap was a perfect fit
