Thread: Low light detail? – Binos vs scope

Think is just my combo of mid-range Nikon scope and shitty unbranded binos. Have noticed in the last 30 mins before dark the detail I see in binos really falls off but it remains clear in scope until last few minutes. As expected being higher quality the scope is always clearer but difference shows much more as light level fades.
Is low light difference caused by 35 binos vs 42 diameter scope, or is it the superior scope glass quality, or is it a combo of size and quality?
It’s obvious regardless of scope zoom. When set at same 7x as binos the difference is really noticeable as light falls.
Scope is Nikon Monarch 5 3-15x40 ED SF and binos are unbranded 7x35.
Would similar value scope and binos perform similarly in low light? Or similar diameter necessary to perform similarly?

FYI I do plan to get better binos sometime however Mrs out of work (anxiety) so budget constrained and these binos were available for the right price, free.
If it’s simply the binos quality I’ll persist as is and use scope at last light with safety on & no ammo in chamber.
If it’s bino diameter I know when I do buy some in future to get bigger diameter, like 8x42 or 10x42.
