For me, I love 82 degrees, it feels just right. any limitations are just limitations and can not be named "favorite", (2) acceptable (not a favorite) eyepiece AFOV depends from nature of observing object. Both have the same true FOV and cover the cluster nicely. The contrast is good and the view is clear from edge to edge. That doesn't happen with 100 degree eyepieces. Building an set of eyepieces takes some time. Don't know if this means that that the actual focal lengths are different? Yes, for standard 1.25" and 2" eyepiece filters. Don, I know the FS size controls the AFOV, but I thought the F/L was inherent to the optical design? The Meade and Omegon represent great values. This particular line saw its sales creamed by the superior ES 82s when the price on the latter was reduced. Bottom Line: Very good performance vs. price. I find that the longer the focal length of the scope, the more I wanted wider apparent fields. They're just too big and heavy and more of a novelty view for me, whereas my 82's are quite comfortable.

Stellarvue SVX127D I like short UWA's as I only use muscle drive mounts, and I don't have a UWA in 4mm. I tested this set on f/6 apo refractors and f/5 to f/6 Newtonian reflectors, concentrating on comparing on-axis and off-axis sharpness. Good correction comes with a price. It eliminates the need to rebalance the telescope. This is not recommended for shared computers. The 4 and the 8mm have barlow lenses in them and they are the same eyepiece other than the barlow lens. Returned it. Good decision! I have the WO versions of these and find them very good, indeed!
