The 90° eyepiece with 1x or 2x magnification fits all polarscopes on Sky-Watcher mounts. It makes polar aligning your mount so much easier!
The eyepiece sleeve securely clamps over the standard polarscope eyepiece using three plastic-tipped, knurled metal thumbscrews. The internal diameter of the eyepiece clamping sleeve is 30.1mm. The plastic tips prevent any damage. For optimum positioning, the eyepiece can rotate 360º around its axis in click-stops. The eyepiece can be switched between 1x and 2x magnifications. The eyepiece is fitted with a fold-down rubber eyecup and can be adjusted by +/- 4 dioptres. The eyepiece can also be used on many mounts from other brands.
A useful accessory that makes polar aligning your mount easier and more comfortable.
