Ostara 20mm SWA70 eyepiece overview and review

Looking through astronomy forums, this eyepiece gets some mixed opinions to say the least. I may be wrong, but I would guess many of the views are from people that have not looked through this model.

For those who have looked through it, they have been impressed with the wide field of view, which far exceeds a standard plossl. Colours , contrast and edge of field quality far outperform plossls in the £20-£30 range.

One of our customers at Northern Optics was so impressed, they bought a second to use with their bino-viewer. Specs are 70 degree apparent field, fully multi-coated optics, solid build and internal blackened edges.
