Observations that you take using the Liverpool Telescope are returned to you in the form of data files called FITS files. You can process a FITS file to make a nice image and carry out measurements but you cannot open FITS using common photo editing software.

It may make more sense to think of a FITS file as a document. As well as arrays of pixel data, it contains lots of other information.

So how do you open a FITS file to see your image? You need to use special software or applications designed to read FITS files. Luckily, the Schools' Observatory have created some for you to use for free!
