New DSLR Air-Mass Corrected Spreadsheet!

I would like to announce that the DSLR Documentation and Reduction Team has released the long-awaited Air Mass correcting spreadsheet in the Intermediate-level Final Reduction tutorial.  If you have been doing DSLR work in the last few months and your target star has been more than 30 degrees from the zenith, we highly suggest you re-reduce your data with this spreadsheet.

There are sure to be a few bugs we didn't get worked out in the tutorial and/or spreadsheet so if you find something please let us know.  If you have any questions/comments, please post them in the photometry forums.
