Great help.  Just what I was looking for.

Wanted more of a technical/historical answer rather than a 'how to'
guide but helpful

Thanks very much. You further clarified a social psychology for me in
noting that most images from space that we see have "been rectified to
be oriented with
north at the top." This leads me to assume that astronauts see Earth
geography in any number of orientations, and may be sometimes confused
at what they are seeing since their view is not the "normal"
North-South position of terrestial geography. The only question that
remains is whether there is a "normal" astronaut orbiting position
(Space Shuttle, Space Station, etc.) that follows a longitudinal path
(rather than latitudinal) and places their cockpit orientation towards
the North Pole rather than the South Pole. This may sound vaguely
ludicrous, but I'm actually interested in knowing if this kind of
orbital orientation is at all considered in space flight for (perhaps)
psychological coherence and/or other communications logic, etc.
Thanks!

Thank you very much for this answer! This is REALLY helpful to me!

That helped. Thanks.

Maniac-ga was quick, through, and explained the solution is such a way
that I could build on it to solve other questions. I was impressed!!!

THanks to maniac and all the other commentors and researchers who
chipped in.  I was able to get what I needed.

Great extra effort on this harder-than-it-looks problem.

The explanation of the code really helped me understand the
functionality of the macros in Excel. I am very satisfied with the
answer I received and will definitely return to use Google Answers
whenever I have a complex problem that needs to be solved. The effort
to answer my question within my suggested time frame is very
appreciated.

Excellent, thank you very much.  I got it to work and i understand how
the chart pulls off the numbers (so if i need to move my chart or add
lines i understand how to make that work).

Many thanks for a comprehensive answer.

thank you maniac for the helpful #comment lines that make clear the
actions invoked by the perl script ... the program ran first time out
of the box and i am going to replace a larger inelegant script with
yours ...

A litle confusing at first, but after trying it, worked great! Just what I needed.

Excellent answer.

BTW, Maniac, I've asked a followup question titled "Looking for
commercial software prgm to see when machines are taken off network". 
As you can see, I'm abandoning my approach of doing it myself.  If you
know of a commercial program, I sure invite you to answer that one.

Exactly what I needed. Thank you!

Thanks, nice enhancement to the comment already posted.

Good solution and extra work put it (beyond searching) ... I
appreciate the example that I could download and modify.

Awesome help from maniac-ga! Not only did he provide the macro, but
also explanations as to what the code did, and how to get it running.
The explanations were so good that I was able to write an additional
two macros myself based on his answer!

Maniac, 

You have thoroughly exceeded my expectations! The solution turned out
to be much harder than I anticipated, but I was able to implement your
solution with little difficulty. The spreadsheet you created was a
great addition and assisted me immensely through the process. It
provided a much clearer answer to the problem than any set of text
explanations/formulas could.

My rotations are now perfectly pixel-accurate and you have saved me a
great amount of time and frustration.

Okay. I see. Thanks for the help.

Quick to reply and seems like a nice person!

Answer was bang on, articulate and made it clear that if it did not
resolve the issue that additional info would be made available.

Script performed very well, I appreciate the additional explaination
of the elements in the code which allowed me to make some additional
adjustments.  Instead of running the script via macro command bar, I
ended up applying the script to an embedded button on the sheet which
would be more understandable to the end user and performed refreshes
more easily.

Exactly what I needed. Good source usage, well written. Included
search words which was very helpful.

Thanks for your help!
It is really great help for me!!!!
