Hi Jerry,
I have put on a few pounds in the past decade, I'm not sure bigger is
better...at least in that case.
There's a Stearman bi-plane on the island here. It did make me think of you
;-)
Regards,
Austin

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

I'm not sure if I've been upgraded or downgraded... I kind of liked the
747.

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.

Austin
