Description
The 15.5mm PF lives in the part of your eyepiece case that gets the most use high enough magnification to resolve detail in deep-sky objects and show structure on planets, low enough that seeing conditions rarely shut you down. If you already own the 25mm PF and you’re looking for a meaningful step up in magnification without a meaningful step up in price, this is it. Same flat-field design, same light weight, same filter threads, and nearly parfocal with the rest of the line.
