Great product Excellent service!
Top notch product; very useful and well built. OPT offered as usual a fast delivery! Very pleased and recommend this product.

Perfect fit for my setup!
I had been searching for weeks for the appropriate accessory to fit my set up, and this part fit perfectly! I received a 2” Optolong L-enhance filter as a gift, but could not use it with my previous set up because I use an off-axis guider (OAG). The Baader protective T-ring adapter fits perfectly on my Canon EOS camera and the filter threads easily and securely to my OAG. If you use a DSLR with a Celestron 8“ edge HD telescope, 0.7 Reducer, and a Celestron OAG, then you absolutely need this part to use any 2“ filter. Thank you, OPT!!!
Baader wide t-ring for eos with 2” nosepiece
Slight lateral play against camera body despite the advertisement. Holds a filter internally but would be inconvenient to field change because it requires disassembly with an Allen wrench. Not something to be done in the dark on a cold night.
