Excellent contrast. Sharp across the full field. Although it does not have the FOV of the 7 Nagler, it is noticably sharper and brighter. Great planetary eyepiece. Barlows very well when the seeing will allow it.
This is my favorite high mag eyepiece. Sharp across the field, bright, and with very high contrast. Excellent performance in both of my Tak refractors and my 10in f6 Dob. Only edged out a slight bit by some of the high end orthos, but the LE-5 has much better eye relief and wider field.
This one really live up to the hype. Outstanding overall performance. Sharp to the edge of the field, very good contrast, and comfortable eye relief. Works equally well in the Dob or the refractor. I think I have a new favorite eyepiece.
When I first received my WO scope I found out how great it was to rotate the eyepiece into any position without having to loosen and rotate the diagonal. A bit too loose on the diagonal or not quite tight enough when re-tightening and bang the diagonal and eyepiece can hit the pavement. Not to mention the rotation marks on that nice diagonal barrel. With the CAA you can rotate the eypeiece (or camera) to any angle and gain a comfortable viewing postion. This is a must have in my book. Be aware that it will add a bit of length to the focus tube, so take that into consideration if (in) travel is an issue.
