Gadget needed, video camera type

Still got me scratching my head~~~~

It's 52 yards to the peak of that house.

My shingles are 11.5 inches between "cracks".

what power did I actually have the scope set on?

Did the power of the camera have any effect?

I can replicate this to discover the near truth.

If your roof line slope is 30 degrees, then I would guess about 6.5 power, the camera magnification will not matter. [img]images/icons/smile.gif[/img]

Dave, I still haven't figured out the shingle size thing, it's got me baffled too. Mine are 13.5" between "cuts", yours are 10.5", I think your neighbor has even a different size... they definitelly don't seem standard anyway! [img]images/icons/grin.gif[/img]

Your scope seems to still have been set on 7 power, 5.5x maybe... depends on if each shingle has about 4" of exposure (measured vertical) and maybe 5.5" in reality like mine. I see they are each about 2 MOA high and 13.5 MOA wide... About all I can tell ya unless you climb up on his roof and measure them for me.

Come on now. [img]images/icons/grin.gif[/img] Get us some more good pics through that R2 while you're at it, this time start easy and work up to the hard stuff!

I was resonably sure I increased the power on that scope before I took that picture but the math seems to indicate otherwise (forgot to take my Alzheimer's meds I guess). So I NEED to do some testing [img]images/icons/smile.gif[/img] (I like testing [img]images/icons/smile.gif[/img] ).

My math seemed to indicate 88 yards assuming the "standard" 5 MOA horizontal. This would put me at 5.9 power on the scope... 52 actual yards / 88 perceived yards = .59 ratio... Tick for NXS is at 10 power so 10 * .59 distance delta ratio = 5.9 power.

How did this thread begin?

I'll find some more stuff to photograph.

I think your strongest evidence may be your own photo of the power ring. The roof line is not perpendicular to your sight line, so like the roof's slope the shingle dimension in the scope will appear smaller than actual, leading you to conclude it is farther away than actual.
