Hi all,

Looking for an approx 17-18mm eye piece to fill a hole in my eyepiece collection but can't decide which one?
Would like to use it in all my refractors f4.5, f5.3 & f8 and needs to be 70-85 deg field of view and a 31.7mm barrel. (Keeping it small in stature for my Borg scope also)
As you can see in my photo I don't mind mixing and matching from Vixen, Taks and Televue eye pieces.
Would also prefer sharp to the edge in all my scopes if possible ?
Have also been leaning towards the Nikon Nav sw 17.5 but not too sure if this would be a good match or not.

Any recommendations would be appreciated.
Cheers.
