the lens come without plastic cap.. make sure you request from seller to add that.. other are very good for the price (4mm) usually needs very powerful telescope so avoid 4mm if you have mediam range one. and the picture quality definitely lose resolution and get dimmer ... i love the product.. thank you seller
This is fantastic! I was able to see more details from Jupiter than ever before with my 4.5" reflector telescope. I had a 9mm eyepiece before but it wasn't a plossl, you can really tell the optics difference at those magnifications. Totally worth the price. This is not an all metal eyepiece like a Celestron, but for the price is fantastic.
