15 Panoptic, 14 Leica, or 13 Nagler T6? I have a 12.5" f/5 Portaball I've rigged for 1X (no 2X barlow) with a TV binoviewer. I love the wide view of the moon at 87X using 18 Radians and want to see it even closer and wider keeping the edge within the AFOV if possibe. Thanks for any input. ...Gary Palmer

I'd go with the 13mm nagler T6 since it will give the largest image of the moon and will still fit neatly within the fov. It will produce a moon image that is a bit over 60 degrees across within the 82 degree fov. There is some geometric distortion with all of the superwide eyepieces but if you limit the size of the moon to 65 degrees or less and keep it fairly well centered, it shouldn't be a problem. No experience with that paticular eyepiece but I've heard that it is one of the better Naglers for binoviewing.
