TPO (6) 65mm X 120mm - 200mm Eyepiece Case

The TPO (6) 65 mm X 120 mm - 200 mm Eyepiece Case:

For those of us who love observing with a telescope, it's common 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 eyepieces looking like new, these two-piece polypropylene twist-lock cases are a perfect protection. The injection-molded polypropylene plastic resists hardening, yellowing and cracking over time. The length of the TPO 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 - meaning it can vary in length. 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 65 mm and varies in length from 120 mm - 200 mm. For best results, measure the widest portion of your eyepiece, as well as it's length, and choose accordingly.

2" Big Barlow Case

I got this particular size bolt case for the 2" Big Barlow that comes with the 2" - 1.25" adapter. I could have got the 120mm but, decided on the 200mm because when the barlow is placed inside I can twist it all the way down and it has a double side of protection. The only thing I have to do is remove the two thumb screws of the barlow and place them in a small zip bag, toss it in with the barlow and fits perfect. I also placed a 6mm of foam at each end for added protection.

Exactly what I wanted/needed

The most common problem associated with having a bunch of eyepieces is how to store them. Luckily, OPT offers just such a way. These eyepiece cases are just the ticket. Correctly sized, durable, dust-proof.

I wanted to give this a great review but it really is only a mediocre case. The plastic is thin compared to others I have purchased. It does the job but don't expect to be wowed.

Always good

Anything you get from OPT is first rate. Wish they were in NY!
