• Colorized header.
• Quick summary + Full header
• Automatic detection of ESO keywords
• Links to ESO archive seeing/prog id pages (when possible)
• Support for multi-extensiom FITS files!
• On-the-fly preview of 2D images!
• On-the-fly preview of 1D spectra (drawn with scaled axes)!
• For 2D images: On-the-fly thumbnail of 1^st extension that contains data
• For 1D spectra: On-the-fly thumbnail of the spectrum
• Display of the value of the "OBJECT" header keyword, with large fonts.

Notes: images pixels are scaled linearly (it produces in general better results than linear or logarithmic-zscaling). If no data are present in the FITS, only the header is shown. Previews are full-resolution images/spectra up to 2000 pixels wide/long. Above that, it is scaled down to 2000 pixels. Users of SAO/ds9.app: If you see the SAO/ds9.app icon in your Finder , you need to open the "Get Info" panel (⌘-I) of the file, and make sure to apply to all files by cliking "Change all...".

The FITSImporter plugin is a Spotlight plugin that allows to make Spotlight queries against dedicated keywords of the FITS header. It provides also additional information in the "Get Info" panel of the Finder (⌘-I). When available, the following keywords are filled:

	Target Name (as a string)
	Naxis (as a number)
	Naxis1 (as a number)
	Naxis2 (as a number)
	Observation Date (as a date)
	Exposure Time (as a number)
	Instrument Name (as a string)
	Detector name (as a string)
	Telescope name (as a string)
	Observatory name (as a string)
	Observer(s) name (as a string)
	Right Ascension (as a number)
	Declination (as a number)
	Equinox (as a number)
	Epoch (as a number)
	RaDecSystem (as a string)
	Local Sidereal Time (as a string)
	Universal Time (as a string)
	Modified Julian Date (as a number)
	Julian Date (as a number)
	Airmass (as a number)
	BZero (as a number)
	BScale (as a number)
	Bitpix (as a number)
