The images that I observed through this TPO 42 mm, 2 inch eyepiece were breathtaking, sharp and flat; especially when combined with the TPO Coma Corrector. I bought this eyepiece to help find objects by star hopping or by using setting circles. However, once I found the object of interest, I found myself staring longer through this eyepiece rather than switching to a shorter focal length eypiece because the view was so beautiful.
I liked the widefield view of the quarter moon. The eye relief is perfect for an eyeglass wearer. And the quality is very good for the price.
This is my favorite eyepiece for wide field viewing. It provides a very sharp image and is easy to use. Use it on my SC11 Edge. Recommend it to anyone needing a wide field of view especially if you are a novice at the art of astronomy.
This has become my favorite eyepiece. Sharp to the edges on an f/6.2 ED refractor. Everyone says great things about the 30mm which I like too but the 42mm is sharper on my scope.
Very nice lens, especially considering the price. The outer edges loose some sharpness but most lenses do. In the majority of the view these are crystal clear.
