I notice that you haven't had any negative comments on your plan. Well, you won't get one from me! I love my TV eps. BUT I still use my GSO plossls to get a little more detail on faint galaxies. When I posed this on another thread, people suggested that having fewer lens elements enabled a little more light to get through and I think this is a good explanation. I wonder if I might invest in a TV 15mm plossl at some stage just for this purpose. But, if you get a Nagler or Ethos, you'll still have the plossls that came with the scope, so you lose nothing. The nagler's wide fields are fantastic!
