Amazing Russian TAL 25mm Plossl And 15mm Kelner Eyepieces/ From TAL M1 Telescope

It is a Russian eyepiece and a decent one it is. This eyepiece comes with a purchase of a Russian TAL refractor or can be bought on its own. It has a plossl&typical 52 degree field of view, excellent eye relief of 19mm and 4 glass elements. In my scope it showed excellent views, but the background was never really black. It was more like a dark brown at best. Contrast was very good. Another interesting feature was that the top eyeglass lens is slightly raised and one should be very careful with the coating. This EP also barlows very well.
