Inserting eyepieces into telescopes
I'm a complete beginner to observational astronomy, so I bought a cheap telescope to try it out. My question is about inserting eyepieces into the holder and fastening them with a screw. Won't the screw damage your eyepieces after a while, no matter how lightly you fasten it? Is there a proper way to fasten eyepieces in the holder that I'm unaware of?
Many thanks
