This is a low cost eyepiece, but how does it perform? Very nicely! It is bright, clear and sharp and has a wide 50 degree apparent field of view! Not bad, but there is more: the eye lens is 3/8" or 9MM in diameter, so it is the size of a normal high cost plossl eyepiece. It also has a rubber eye-cup, 3 coated glass lenses, good eye relief of about 9MM, and a chromed metal barrel with filter threads! I am not saying this is as good as a high end plossl but it is not bad at all, either. If you want a very nice high power eyepiece for under $10 brand new, i don't think you will find any other eyepiece that is even close in overall performance and value. This also has a protective plastic case included. This eyepiece is a really excellent deal. Shipping is free in the CONUS -- email for foreign shipping fee.
