[Aavso-photometry] Airmass / Extinction Calculation

[Steve Robinson]

For anyone using Bisque's TheSky, Airmass is computed as an element of their object description screen.  You must have the correct date/time, and position input however, then just find your object and view the pop-up window.  Airmass will be there as one of the fields.
