    Is a 7X scope worthwhile?

    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.
