TPO 2-Inch Dust Plug

TPO Dust Plug for 2" 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 cover 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 find their way into your optics.

We've all been there... Done that. Sure, a ziploc bag or a pill vial 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?

Fashioned from flexible plastic, TPO male replacement dust plugs for focusers, barlows, diagonals and adapters resist hardening and cracking with time. Unlike a pill vial, 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 and optics easy and quick. Why take a chance of accidentally dropping something inside your telescope? Buy an extra and you're always covered!
