QFits README

QFits is a viewer for the standard astronomical data format FITS. It has the 
typical astronomical functionalities like: one click contrast enhancement, 
colormaps, star parameter identification...  Unlike the most popular viewers (ds9, gaia)
it makes use of all the hardware that modern computers offer. Modern graphics
hardware makes smooth contrast enhancement over the full depth of the image 
possible, it can interpolate between pixels in real time, ... QFits offers all
functionality that other viewers have, but faster and more. It can for instance
smoothly view huge (gigapixel) images from modern wide field cameras that are to large to fit
in the computer memory.

Modern software packages make the extension of QFits possible without
recompiling the whole program.  Qfits extensions can be written in as little as
20 lines of C++ or 10 lines of Python code. You can for instance write an extension
for focusing your telescope based on a series of exposures that an end user only 
has to click.  The standard package comes with 
dozens of extensions that you can use or ignore without slowing down the 
performance.
