      5.0 25mm Vixen Lanthanum

      Very pleased with this eyepiece. It is nice and bright and makes very nice views of fainter objects. Compared to my TV Plossls it is more transmissive with crisper color, but it has some pincushion across the FOV and doesn't manage stray light as well. The pincushioning is noticeable but does not detract from the view for me.
      It has extremely nice contrast and brightness, these are it's strongest points. I am using an 8" f5 reflector and really like this eyepiece for lower mag gawking and scanning.
      Would buy others in the line.

      5.0 Vixen 25mm SLV

      Pros:

      Comments:

      The 25, 5 and 4mm are the best of the SLV series in my opinion. With the 25mm SLV, background on star clusters is dark and the stars are bright and sharp. Unlike widefield ep's, there is no distortions that I can see from the center to the edge of the FOV. To me a very nice clean, natural view. During the day, excellent sharp contrasty views through two different refractors at 26x & 32x.
      I like the long eye relief which makes for relaxed long term viewing. I like the twist up eyecup feature which can be adjusted up to a comfortable height. It is just the right tension so it stays where left at and when I place my eye on it. The 25mm has the tightest eyecup of the series and has been getting the most use. I like how it feels solidly built, quality design and will last for years. This is important to me because 2 of my big name ep's have already had to be replaced in a short period of time.
