[QUOTE="TheLBLman, post: 1986684, member: 1409"] Those are good glass, but cannot be good in low light. Either go down on the magnification, or go up on the size of the objective. For the most ideal view, you want an "exit pupil" of at least 5.0. With extremely high quality glasses, you can still have acceptable low-light viewing with an exit pupil around 4.5 to 5.0. On these Zeiss 10 x 25's, the exit pupil is listed as only being 2.5. Not sure just how important the low-light capabilities are to you, but these Zeiss 8 x 30's would be considerably better in low light (exit pupil rating is 3.75).
