Nightforce NX8 1-8 Scope

Hey, my apologies for a dumb question:

"Eye box" is .... what, exactly?

And is this different from the distance from eye to optic?

Thanks.

That’s eye relief. Eye box is defined as the amount of "allowable error" in a shooter's eye relief position, yet still offering a clear target image.
The eye box is a function of the allowable lateral and axial movement of the eye pupil while still maintaining a clear view of the target. It is dependent on min/max values for eye relief, EP diameter and the diameter of the eye pupil.

In other words the scope shadow left to right and the eye relief being to short

Have you seen the image through a razorII? Hardly any scope shadow at all but it’s second focal plane

[MikeF]

That's very helpful and thanks and now....second focal plane v. first....I've read about this but always forget.

OK, so ... just watched Vortex's video on FFP v. 2FP....seems on a LPVO the FFP makes a bit more sense so you get a nice large reticle at 1x.

What am I missing? I think I can see the point of 2FP on higher magnifications of over 8 or 10....but seems FFP makes a lot of sense with a LPVO.

Nightforce NX8 1-8x24.

Sorry, are you referring to the NX8? I'm still trying to decide, but now find myself leaning toward the Nightforce.

Just found this really interesting post with comments following on the ATACR 1-8

Mount came in today, A496 Unimount.

To say this scope is finicky is an understatement in regards to diopter adjustment and eye relief. That is, until you get it in a mount and put it on your rifle.

Once I got the eye relief set and felt comfortable with the placement of the mount, I torqued everything to spec and did a few presentations with the rifle.

Eye relief is near perfect, diopter adjustment is excellent, the fisheye that I was experiencing is gone.

The best advice I can give someone who is a first time buyer of this particular scope; get it out of the box, set the diopter as best as you can and then get it into a mount. Night and day difference.

I’ll try to get up some pics later.

I would even say that the diopter shouldn't be set until you have it mounted and eye relief set. Not saying you can't do it first, but it would be much more efficient (and possibly better off) to set it in a mount first.

I'm assuming you should adjust eye relief in the position you will be shooting it most often, correct?
