He also includes a bit of history of the design use and spot diagrams at the end.

I would agree that a better comparison such as this would likely be best with at least 3 observers of differing age groups and skill levels.
Agreed, LF. I’m slightly surprised that the GSOs fared so well but only slightly. That’s because my own comparison of the TV Ploessl line and the Vixen NPLs showed the Vixens to be quite good and not just good for the money.Lady Fraktor wrote: ↑Mon Apr 19, 2021 9:47 pmI would agree that a better comparison such as this would likely be best with at least 3 observers of differing age groups and skill levels.
But I have found that some of my findings are the same or very closely match those stated in the review.
At one point I have tested side by side TV, Vixen and Meade Plossls. While they all performed good for the money, in my scopes and for my eyes TV were sharper at high powers followed by Vixen and then Meade.notFritzArgelander wrote: ↑Mon Apr 19, 2021 11:00 pmAgreed, LF.

Which goes to show that the best eyepiece advice is always "try before you buy".Bigzmey wrote: ↑Mon Apr 19, 2021 11:15 pmAt one point I have tested side by side TV, Vixen and Meade Plossls.

On faintDSOs Meade had the best transmission, while TV (modern version) the best contrast. NPL were a good balance of two.
Not surprised if they similar in performance to my SLVs. I am not a big fan of modern TV Plossls. Had complete set at one point but sold them one by one. Circle NJ smoothies is a different story.Lady Fraktor wrote: ↑Tue Apr 20, 2021 4:12 am Have you tried the older Vixen LV eyepieces? I still enjoy them quite a bit and I actually replaced most of my TeleVue Plossl with them.
Except the TV 11mm, that is a great eyepiece.
Vixen LV 2.5mm - 25mm are 5 element/ 3 group design (that seems familiar...)
