With unsurpassed optical clarity and the shortest focal length in the XW series, the XW 3.5 offers a 70 degree field of view for easier viewing. All of our eyepieces are constructed with a high-refraction, low-dispersion lanthanum glass that consistently delivers bright, high-resolution images with minimal distortion. In addition, all XW series eyepieces are built to JIS Class 4 weather-proof standards which increases their durability in less than ideal conditions. Designed for use with a wide range of telescopes and PENTAX brand spotting scopes, the XW series eyepieces are a clear choice for ground and astronomical applications.
Pentax 3.5mm XW Eyepiece - 1.25"
Compatible with the following: PF-65 and PF-65 ED II series spotting scopes, PF-80 series spotting scopes, PF-100 series spotting scopes

This EP will give you the absolute BEST planetary views you will ever see. I've gone through a dozen or so high magnification Eps and none of them performed nearly as well as this 3.5mm. I'm talking about major, well-respected brands that could not match the Pentax performance. I now own 4 Pentax XW's, including the 30mm, 20mm, 14mm, and 3.5mm. These come with a limited lifetime warranty from Pentax, they are weatherproof, and they have crisp, bright, high-resolution images that will blow you away. You cannot find a better eyepiece, period.
