[QUOTE="OPTIC_NUT, post: 3257585, member: 121951"] I really like precison 7-degree 7x50s. Both the 7 and the 50 give the eyepiece reason to have a bigger FL and thus big eye relief. I did not notice the narrow view on the 7x50 Aculons! Huh...that's a throwback to the 50s. That does allow an even flatter field than just cutting 6-1/2 degrees out .. interesting. They would stretch a Kelner, probably. Very high contrast. Yes...maybe nice for the night sky. Still claustrophobic. In the shop I was just struck by the flatness. There are 7.1s sharp to the edge. Some go 5-element (very flat, rare siblings of the 7x35 Featherweights), others add a little curvature to the top surface. [/QUOTE]
