We have only scratched the surface of what is possible with PSP-8. I purposely avoided using many of the tools available in order to keep this as simple as possible and still show basic application steps. As you develop your processing skills. the use of such things as "histogram adjustment", "levels", "layers", etc. will be of great use in processing astronomical images. For now all I wanted to demonstrate is basics that will get you up and running. I hope you find this presentation helpful.
