Stunning EP !
Friday, 21 September 2018  | 

Tried on a VIXEN BT81S-A bino-telescope, and compared to VIXEN's LV10mm views of the moon are crisp and clear. Mars can be observed with the limitation of the low magnification (given by the bino-telescope). Eye relieve is convenient and the eye-guard very practical. These EPs are very well made (fit and finish) and optically perform very well. On my bino-telescope, magnification is x56, far above the maximum magnification recommended by the manufacturer (x48) but I cannot see any severe degradation. For the price... you will not find anything better.
