I have used this eyepiece in a 12" F#5 Meade Lightbridge. It is a wonderful eyepiece. The Instajust feature works very well, And with 17mm eye relief its perfect for eyeglass wearers. I would highly recommend the 17mm Nagler. I feel its worth the extra cost to use an eyepiece you can have confidence in. Eye position is important, But after the first night out you'll get the "hang of it".
Pros: Excellent eyepiece
Cons: The cost is high, But the quallity is also high
