TPO 1.25-Inch Dust Plug

TPO Dust Plug for 1.25" Focusers, Diagonals, Barlows, Adapters and More

It's the end of the observing night and you reach your hand into your pocket to retrieve the dust plug for your telescope's focuser. Oh, no it's gone... You dig through your accessory case. You search the ground frantically with a flashlight. You pat your pockets down again. Why? You realize that without the dust plug that all manner of things - from dust to bugs - can now enter your optics. 

We've all been there... Done that. Sure, a Ziploc bag and a 35mm film canister will work in a pinch, but not in the long haul. Why settle for whatever when you can get replacement dust plugs for your telescope's focuser, barlow lens, diagonal or adapter for about the price of a cup of coffee? At OPT, we have these specially made just for our customers, because we understand what it's like - just as we understand the importance of sealing up your equipment when not in use.

Fashioned from flexible plastic, TPO replacement male dust plugs for focusers, barlows, diagonals, and adapters resist hardening and cracking with time. Unlike a film canister, the TPO Dust Plug is made specifically to fit inside your optics with a shallow depth to keep from touching interior parts. We've even added a special easy grip top to make removing and inserting the replacement dust plug into your telescope's focuser or optics easy and quick. Why take a chance of accidentally dropping foreign debris inside your telescope? Buy an extra and you're always covered!
