I have the Steiner nighthunters 8x56's. I like em' and they definately gather some light. I hunt yotes using just the moon as a light source. Some important things to consider are thesure they have multiple lens coatings and a the bigger the exit pupil the more light that will reach your eye. An averagehuman eye opens to around 5mm so anything much over that we can't beneifit from anyhow. To get the exit pupil you divide the objective by the power, so mine have an exit pupil of 7mm. 56/8. 10x50s=5 and so on. I'm sure there are other good brands out there, I got the steiners cause their lightweight, rugged, have a good warranty, and had eyecups that fit my face well. Try em all out, I suggest going with some that are comfortable to look through and meet some of your minimum performance requirements. Good luck.
