My DIY telescope adapter mount doesn't work with this 6mm eyepiece because the light cone focuses further away from the surface of the eyepiece - which is great if you're looking through the eyepiece while wearing glasses, but bad for trying to take photos while resting the camera directly on the eyepiece.
Ok that was me trying to describe it, and then I looked it up... it's called "eye relief" and it "measures the spacing from the last surface of the eye lens of an eyepiece to the plane behind the eyepiece where all the light rays of the exit pupil are visible" (Celestron.com). My 6mm eyepiece has 14.8mm eye relief which is comfortable so you can blink and not worry about touching your eye directly to the glass.
