Austin,

Upgraded.  The A-380 is a much bigger jet transport.

Hi Jerry,
I'm not sure if I've been upgraded or downgraded... I kind of liked the 747. Regards, Austin

    Austin,

    I see that Austin (A-380) is still misspelling LENS.

    But other than that, your assumptions are absolutely correct.

    Hi,

    Also, the shims I've heard people mention (Dymo label take, and paper) are
    unstable over time.

    Getting a focusing screen as accurate as can be is a two step process.  The
    shims are more for getting the screen planar (that corner to corner the
    screen is in focus), and that's step one.  Then, the overall focus has to be
    adjusted to match the taking lense.

    Regards,

    Austin
