I am looking to replace my 15mm and 11mm Televue Plossls, and one or all of my 8mm, 5mm and 3mm Radians, with either Naglers or the new Deloses. I am using an 18" f/4.3 Dob, currently without a Paracorr (but I am looking to get a Paracorr some time). What I am aiming to do is probably replace all 5 eyepieces with just two or three new ones.
Would you go for Nagler or Delos? Ethos eyepieces are beyond my price range, at the moment, each one costing twice as much as a Delos.
