Excellent Tri-Bahtinov Masks

Laser cut and sharp, gives a nice easy to see diffraction pattern, and the adjustable nature makes it a breeze on multiple OTA's. A+

Good, but not perfect

I was very excited to received the focusing mask the other day. I tried it out that night and all went well. It fit my scope nicely and I like the extra spikes in the pattern. Unfortunately, I left it out on the table next to my scope in my backyard, as I have done with some other black plastic Bahtinov masks that I have used, and it warped quite a bit during the day. That's probably my bad, but I didn't expect it to happen, given my experience with others.
