TPO (2) 42mm X 60mm - 80mm Eyepiece Case

Keep your eyepieces looking like new with these two-piece polypropylene twist-lock cases provided by TPO!

TPO 80 mm Eyepiece Case Features

  • Its injection-molded polypropylene plastic resists hardening, yellowing, and cracking over time. 
  • The length of the TPO eyepiece cases is variable due to the unique twist-lock mechanism. Simply twist the top piece down until your eyepiece is snug and secure.
  • The hexagon-shaped end prevents the OPT 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 water-resistant. Help stop lint, fingerprints, dust, and dew from getting on your favorite telescope and spotting scope eyepieces!

Note: This model has a diameter of 42 mm and varies in length from 60 mm to 80 mm. 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 8 mm, 11 mm, 15 mm, 20 mm, & 25 mm Plossls, 4.8 mm Nagler, and 15 mm Panoptics.

Used for another purpose - perfect!

Good. I used it for something other than what it was designed for and it worked perfectly.

Just what, astronomer ordered

I needed some good quality eyepiece cases to make sure that none would be broken or exposed to rough-handling, and those that I purchased from OPT fit the bill perfectly. Very pleased, indeed!

Perfect Fit

I bought this for the 25mm eyepiece that came with my Celestron Nexstar 4SE and it fit great. It easily resizes for different size eyepieces.
