First of all, it sounds as if you have some sort of systemic error if your sights are always coming out with the same 0.5 or 1.0 inconsistency.

Second, the usefulness of a 7x scope will clearly depend on the stability of the platform you're on (as well as the stability of your hand).  I've taken shots from my 36' sailboat and in anything but a dead calm it rocks enough that it's hard to get a good shot even with a 1x scope.   You're trying with an AH, presumably on land.   Might work there, doubt a 7x scope would work at sea unless you're on a very large ship.

Hi all,
        My question du jour is:  Is a 7X scope worthwhile?
I have been taking as many AH practice sights as I can lately, (when the weather cooperates)
I have also been doing slope fits for my multiple sights and find my data consistent.
My problem seems to be that I am always 0.5 to 1.0 Towards, I am using the 'set & wait
technique' and letting the sun come down to the AH image. I do a slow rocking of the
sextant and mark my time at what appears to be the instant of touching. I think I read once
(in a NavList post?) that a 7X scope could improve sun & moon sights by virtue of the fact
that the image would be bigger. Obviously (I think) my images are not actually touching - even
though I believe they are. My eyes might benefit from the increased size. What say the jury?
Last question: Has anyone here ever cannibalized a 7X binocular to make a 7X scope?
I think it is possible and some of the prices I've seen for 7X scopes would make them
prohibitive on my budget.
Thanks!
       ~Greg
