Great! Good for organizing my eyepieces safely.
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.
These work just right. Some brands are hard to spin, but these are a breeze! Thanks!!
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.
Anything you get from OPT is first rate. Wish they were in NY!
