Image Processing and Analysis

Student using the NSO

When astronomers get their image data from a telescope or satellite, they want to make measurements in order to do some science. To do so, they use special computer programs called Image Processing or Image Analysis software.

This software lets users take the huge grid of numbers that make up each image and turn them into a number of measurements, such as the brightness of a star or the size of a galaxy. They can also use the software to study the images in a lot of detail and find out much more about them than from just looking at a normal picture.

The NSO have developed a dedicated image processing package, called LTImage, to help you study and conduct measurements on images from the Liverpool Telescope. The LTImage software also allows you to scale the images and use false colours in order to see more detail.


Please note that over the weekend of the 26-28th May 2017 we will be switching over to our brand new website - during this time there may be periods where the site is difficult to access, and users will be unable to request observations from the telescope. Please bear with us during this time. All should be back up and running by the 29th May 2017.
