' Usage: cscript create.vbs
' Example: cscript create.vbs testimage.fit
'
' Uses the ASCOM FITS image driver
' --> http://www.easysky.de/ASCOM/Image/FITS.htm
' to create a new FITS file from scratch
' and sets some example properties.

' A pseudo image is obtained from the CCD camera simulator
' --> http://www.easysky.de/ASCOM/Camera/Simulator.htm
' which implements the current Camera standard proposal
