Thanks. It’s the only one I’ve ever seen. The Orion version is equivalent to the Vixen NA120, this is the 120S. It’s focal length is 800mm so F6.67.
I'm confused concerning Orion-branded Vixen. In your post #2 you agree that you have a Vixen 120S with five lenses and that it's better than the "Orion-branded Vixen 120mm Neoachromat" you got from Orion back in 2001. Was there Orion or Vixen on the tube? How can it be Orion and Vixen at the same time? What was it's official name: Orion NA120?
Furthermore, I'm confused concerning the S and SS versions. The Vixen Neoachromats were called Vixen NA[aperture]SS, weren't they? So the Orion Neoachromat telescope you had was an SS version as well?
And the wonderful telescope you have now is a Vixen 120S which is not a Neoachromat. Was there also a 130S version of this?
