Please note that the above is just for my skies where the average SQM reading is about 16. I'd imagine that the 10x35's significant reach advantage would improve under darker skies where the balance may very well tip in its favor.
I live in Tokyo's "Opposite World" by comparison. My SQM-L readings on best nights will be over 21. Some members here can do way better than that. Best ever from home was 21.76 looking east, but frequently 21 or less because LP is increasing here as well as common transparency issues. Half a day's drive to central Nevada is like that over the whole sky dome; seen up to 21.85 there When clouds form overhead, they're black against a brighter, star filled sky like dark nebulae.
The 10x35s spend a lot of time around my neck as finder binos while using scopes or mounted binos. From home, the 10x35s smallish exit pupil is surprisingly potent and I prefer them over the 8x. Great contrast helps. They just go deeper and 7° is still wider than a typical finder scope, anyhow. They can show small, faint little M objects like M1 and M78 on a transparent night. In comparison, though, the 10x42Ls clearly go deeper. Exit pupil still matters at equal magnifications. They actually are a bit sharper and certainly have flatter focus across the field than either EII. You'll never forget you've got them around your neck like I do with the EIIs!
Enjoy using your fine optics; you, myself and many of us here have reason to be counting our lucky stars every night!
