Used for securing any 1.25" eyepiece or accessory in a 2" focuser.
I tried numerous cheap adaptors that never worked properly before finally buying the Baader adaptor. They are the best on the market. I have a few of these, so just thinning the collection.
It has three marks around the body in the anodising as shown where I had a par focal ring attached. Comes with all original packaging.
