Product Details

  • For those of us who love observing with a telescope, it's not uncommon to put an eyepiece in a pocket or stick one in an accessory pouch. But, not every telescope eyepiece comes with a plastic case. Zippered plastic bags and the original cardboard box is fine for awhile, but they wear out and aren't always convenient. Stop now and protect your eyepiece investment with a threaded plastic eyepiece case from TPO!

    If you want to help keep your Tele Vue 35mm Panoptics and 31mm Nagler eyepieces looking like new, these two-piece polypropylene twist-lock cases are the perfect protection. The injection molded polypropylene plastic resists hardening, yellowing and cracking over time. The length of the OPT threaded eyepiece cases is variable due to the unique twist-lock mechanism,. You simply twist the top piece down until your eyepiece is snug and secure.

    The hexagon-shaped end prevents the TPO plastic eyepiece case from rolling around on an observing table or when stored loosely in your accessory case. These screw-top eyepiece cases are sturdy, and while not waterproof, are definitely water resistant. Help stop lint, fingerprints, dust, and dew from getting on your favorite telescope and spotting scope eyepieces!

    This model has a diameter of 85mm, and varies in length from 120mm to 200mm. For best results, measure the widest portion of your eyepiece, as well as it's length, and choose accordingly. Common eyepieces that will fit in this case are: Tele Vue 35mm Panoptic and Tele Vue 31mm Nagler.

This is a BIG case

I needed a case for the Celestron Luminos 2.5x Barlow. This case has the necessary diameter to accommodate the lens and two its thumb screws. When I opened the box-- Oy! -- at first, I thought I ordered the wrong item or it was shipped by mistake. This is a large case. Barlow fits with oodles or room. The case also fits my telescope accessory case, so all ends well.

Opens and closes smoothly which is unusual for this size

Excellent bolt cases for this size! This is the first time I have been able to open and close a case this size without a struggle. Usually you are fighting a very high friction plastic where the plastic screeches upon turning and is a battle to open. If you need EP cases that are a pleasure to open and close, I recommend buying them at OPT



I bought a couple of these large eyepiece cases for my larger (and fairly expensive) 2 inch Tele Vue and Meade eyepieces. The cases work great and are just the right size for these eyepieces and I feel so much more secure knowing that they are comfortably protected inside them during storage and transportation.
