This is a high-quality Antares 1.25 25mm Plossl eyepiece with focusable crosshairs (single), perfect for alignment and tracking. To obtain razor-sharp focusing of the crosshairs, merely turn the upper part of the eyepiece.
The W70 series eyepieces offer extra field and extra eye relief without sacrificing image quality. Many observers don't like having their eye too close to the eyepiece, on average, the W70 series oculars have an eye relief of 15mm.
Absolutely astonishing quality eyepieces. When compared to eyepieces almost three times their price, the Antares Speer Waler were up to the same standard. We have personally tested these against much more expensive eyepieces and we have found that these give equal, if not better views, so grab yourself a bargain today !
