Rifle Scope question about tube diameter

I'm going to keep this short- Do you do any of your own critical thinking? The objective is only part of the "window" to your eye when dealing with optics. Build a pinhole camera. It will help you to understand. Do some independent research.
Or you can continue accepting the word of a corporate ad-man on YouTube whose job is to break things down into simple buzzwords to get folks to buy their product

The barrel diameter CAN affect certain performance criteria IF the manufacturer takes advantage it. It's true that the nodal point of the image is very tiny. However, as the incoming image becomes larger both toward the front and rear objectives the narrower barrel MAY limit field of view among other things. Does anyone HATE those scopes with darned narrow field of view making it difficult to keep the image from disappearing when your eye shifts the slightest bit off-center? I'm sure that too small of a darrel diameter isn't always the only causal factor for narrow field of view but I'm nearly certain it is with many scopes.

Haxby, You said:
Haxby, You said:
but you know very well that is not what I suggested to do.Practicing pointing a gun at your friend in the dark ties for the dumbest idea I ever heard.
"So, I would say take your existing rifle and optics set-up to a farmer's field or woods at dusk set up a light brown target... If you want, have a buddy with a flashlight stand down near the target (chamber and magazine EMPTY!)... then have him turn on the light so you can see where you were aiming."

aperture
Mistwolf is correct. They are both apertures, as are a number of other components in the scope. The term "aperture" is a general engineering term that applies mathematically, as in optics, in such diverse fields as radar dishes and radio antennas. Those have nothing that looks like a lens or a tube, yet they have apertures.

Haxby,
Dude! (or Dudette?), I did specify using a "target", maybe like this:
And I did mean to point the flashlight at the target, which was obvious. No need to point (an unloaded) rifle at a friend, which I am reluctant to do even when cleaning a known-cleared firearm on the bench. Safety is as safety does, always, whether it ought to matter or not.
That safety public service announcement out of the way, we have strayed far from the OP's point.
