This eyepiece has the largest true field possible for 2" eyepiece holders -3 times the field area of any 1 1/4" eyepiece. Field is wider than the 31mm Nagler Type 5 but at a fraction of the cost.
The 55mm Plossl is great for a long focal ratio refractor, Schmidt-Cassegrain, or Maksutov-Cassegrain.
The focal plane is placed at the end of the barrel to minimize vignetting.
Performance with Schmidt-Cassegrains is remarkable since it avoids the image degradation and severe vignetting which occurs when using telecompressors.
Long eye-relief for eyeglass wearers.
Great for deep sky fans. Ideal for capturing open clusters such as the Pleiades, viewing emission and reflection nebulas in their entirety, scanning large and faint nebula remnants such as the Veil, etc.
If you have a long focal ratio scope with a 2” focuser this is a terrific way to get the most out of it.
Excellent condition. Caps included.
I no longer have the box as I keep it in a soft eyepiece case.
